POTASSIUM PEROXYMONOSULFATE

Potassium Peroxymonosulfate is a powerful, non-chlorine, inorganic oxidizing agent with the formula KHSO₅, the mono-potassium salt of peroxymonosulfuric acid (Caro's acid), commercially supplied as the stabilized triple salt Oxone with the formula 2KHSO₅·KHSO₄·K₂SO₄, presenting as a white, odorless, free-flowing crystalline powder that dissolves readily in water to form an acidic solution, with a high redox potential of +1.81 V that underpins its broad utility in disinfection, water treatment, pool shocking, organic synthesis, cleaning, and environmental remediation applications.
Potassium Peroxymonosulfate is distinguished from chlorine-based oxidants by its ability to rapidly oxidize organic contaminants, kill bacteria and viruses, and break down chloramines without producing strong chlorinated byproducts, strong odors, or bleaching effects, making it the preferred non-chlorine shock treatment for swimming pools and the active ingredient in a wide range of broad-spectrum farm, environmental, and surface sanitizers.
Potassium Peroxymonosulfate is classified as a corrosive solid with oxidizing properties under GHS, transported as UN 3084 (Class 8, subsidiary risk 5.1, Packing Group II), and identified in major regulatory inventories including TSCA, Canada DSL, and OECD HPV list, with a GHS classification of Ox. Sol. 1 (H271), Acute Tox. 4 Oral (H302), Skin Corr. 1A (H314), Eye Dam. 1 (H318), Resp. Sens. 1 (H334), Skin Sens. 1 (H317), and STOT RE 2 (H373).

Potassium Peroxymonosulfate has the IUPAC name potassium peroxysulfate (PubChem: potassium hydroxy sulfate), InChIKey OKBMCNHOEMXPTM-UHFFFAOYSA-M, SMILES OOS(=O)(=O)[O-].[K+], PubChem CID 11804954 (pure compound) and 23712892 (composite), UNII 040ZB27861, CompTox DTXSID1034840, ECHA InfoCard 100.030.158, EC Number 233-187-4, ChemSpider 8053100; the crystal structure of the monohydrate has been confirmed by X-ray crystallography, revealing a tetrahedral sulfur center, an O-O bond length of 146 picometers, and an SOOH dihedral angle of 90°.
Potassium Peroxymonosulfate is a constituent of the widely used commercial oxidizing agent Oxone (triple salt 2KHSO₅·KHSO₄·K₂SO₄), which stabilizes the active peroxymonosulfate component by combining it with potassium hydrogen sulfate and potassium sulfate; organic-soluble derivatives of peroxymonosulfate include the tetra-n-butylammonium, tetraphenylphosphonium, and benzyltriphenylphosphonium salts, and the ammonium and sodium salts of HSO₅⁻ are also known.

Potassium Peroxymonosulfate has been investigated for delignification of wood pulp and for selective oxidation reactions in organic synthesis; its high redox potential (+1.81 V) makes it one of the most powerful inorganic oxidants available in stable solid form, capable of oxidizing alkenes, converting sulfides to sulfoxides and sulfones, oxidizing amines, and epoxidizing double bonds under mild conditions without the handling hazards of liquid persulfuric acid.
Potassium Peroxymonosulfate is hazardous if handled incorrectly: it is a strong oxidizer that intensifies fires involving combustible materials, it is corrosive causing skin burns and serious eye damage, it is a respiratory and skin sensitizer that may cause asthma-like reactions on repeated exposure, and it must be strictly segregated from reducing agents, organic materials, combustible substances, metal powders, cyanides, halides, reactive metal salts, and strong acids.

Uses of Potassium Peroxymonosulfate:
Potassium Peroxymonosulfate is used as a non-chlorine pool shock treatment to rapidly oxidize organic waste, body oils, sunscreen residues, nitrogen-containing compounds, and other contaminants in swimming pool and spa water without producing chloramines or their associated irritating odors, eye irritation, and skin effects, enabling swimmers to return to the pool within 15–30 minutes after treatment rather than waiting overnight as required with chlorine shock.
Potassium Peroxymonosulfate is used as a broad-spectrum antimicrobial and disinfectant active ingredient in farm and agricultural sanitizers, veterinary sanitizers, environmental sanitizers, hatchery disinfectants, and poultry and livestock facility cleaners, where it kills bacteria (including MRSA, Salmonella, E. coli), viruses (including avian influenza, foot-and-mouth disease virus), fungi, and mycobacteria at low concentrations through the generation of reactive oxygen species.

Potassium Peroxymonosulfate is used as the active ingredient in pool and spa water treatment products including non-chlorine shock, monopersulfate compound treatments, and oxidizing supplements that maintain water clarity, destroy organic contaminants, reduce combined chlorine (chloramine) levels, and restore free chlorine effectiveness without raising chlorine residual levels.
Potassium Peroxymonosulfate is used in denture cleaners, oxygen-based laundry bleach formulations, scouring powders, and household cleaning products as a safe, effective oxidizing cleaning agent that removes stains, brightens fabrics and surfaces, and destroys odor-causing compounds without the yellowing or fabric damage associated with chlorine bleach.

Potassium Peroxymonosulfate is used in organic synthesis as a stable, selective oxidant for a wide range of transformation reactions including epoxidation of alkenes, oxidation of sulfides to sulfoxides, Baeyer-Villiger oxidations, oxidation of functional groups, and as a mild alternative to stronger and less selective oxidants such as mCPBA, OsO₄, and peracids; it is particularly valued for reactions requiring mildly acidic aqueous conditions.
Potassium Peroxymonosulfate is used in printed circuit board (PCB) manufacturing as a micro-etchant for copper surface preparation prior to lamination, a chemical cleaning agent for circuit board surfaces, and as a component of PCB etchant formulations where controlled, uniform copper removal is required for precise circuit feature definition.

Potassium Peroxymonosulfate is used in water and wastewater treatment for oxidation of organic pollutants, taste and odor compounds, and emerging contaminants; in environmental remediation for in-situ chemical oxidation (ISCO) of soil and groundwater contaminated with chlorinated solvents, petroleum hydrocarbons, and other organic pollutants; and in municipal water treatment as a supplemental oxidant.
Potassium Peroxymonosulfate is used in the semiconductor, electronics, and photovoltaic industries for wafer cleaning, etching control, surface preparation, and chemical mechanical planarization (CMP) slurry formulation, where its controlled oxidizing activity and compatibility with aqueous processing environments are critical.

Potassium Peroxymonosulfate is used in the pulp and paper industry for delignification of wood and as a bleaching agent in pulp treatment processes, exploiting its selective oxidation of lignin chromophores with less damage to cellulose than chlorine-based bleaching agents.
Potassium Peroxymonosulfate is used in laboratories as a clean, stable, storable oxidant for analytical applications, for the decomposition of organic matter prior to analysis, for the preparation of persulfate standards, and as a source of sulfate radical anions (SO₄•⁻) in advanced oxidation process research and environmental chemistry studies.

Benefits or Advantages of Potassium Peroxymonosulfate:
Potassium Peroxymonosulfate provides powerful, broad-spectrum oxidation at a redox potential of +1.81 V in a stable solid form that can be stored for extended periods without the instability, volatility, and handling hazards of liquid peracids, hydrogen peroxide solutions, and other liquid oxidants, making it the preferred choice for applications requiring reliable long-term oxidant storage.
Potassium Peroxymonosulfate produces no chlorine byproducts, chloramines, trihalomethanes, or strong odors when used for water treatment and disinfection, enabling its use in applications where chlorine odor, bleaching, and regulatory limits on chlorinated disinfection byproducts are concerns, and allowing rapid re-entry to treated facilities.

Potassium Peroxymonosulfate is compatible with chlorine in pool water — it does not destroy free chlorine but instead destroys chloramines (combined chlorine), effectively regenerating free chlorine and improving chlorine efficiency, making it an ideal supplemental shock treatment alongside conventional chlorine-based pool maintenance programs.
Potassium Peroxymonosulfate decomposes to sulfate-containing products (potassium sulfate, potassium hydrogen sulfate) after its oxidizing action is complete, leaving no persistent toxic residues in treated water or on treated surfaces, which supports its use in food processing, agricultural, and environmentally sensitive applications.

Potassium Peroxymonosulfate is available as a stable, free-flowing white crystalline powder that is easy to handle, measure, dissolve, and apply, with consistent active oxygen content that facilitates accurate dosing across pool, sanitation, and chemical processing applications.
Potassium Peroxymonosulfate acts rapidly upon dissolution, initiating oxidation immediately without requiring activation by light, heat, or additional catalysts, enabling fast treatment turnaround in pool shock, disinfection, and synthesis applications.

Features of Potassium Peroxymonosulfate:
Potassium Peroxymonosulfate is a white, odorless, free-flowing crystalline powder with a density of approximately 2.15 g/cm³, highly soluble in water, forming an acidic solution (pH 1–2 in concentrated solutions), with a high active oxygen content, and is non-combustible but strongly intensifies combustion of organic materials and combustible substances.
Potassium Peroxymonosulfate has a molecular weight of 152.17 g/mol for the pure KHSO₅ compound and is commercially supplied as the triple salt Oxone (2KHSO₅·KHSO₄·K₂SO₄) with an active oxygen content of approximately 4.7% (pure compound: 10.5% theoretical active oxygen) and a total available oxygen content specified by commercial suppliers for pool and disinfection applications.

Potassium Peroxymonosulfate is stable under normal cool, dry, sealed storage conditions but decomposes slowly above approximately 50°C, is destabilized by moisture and contamination, and reacts vigorously with organic materials, reducing agents, and certain metals; containers must be kept tightly sealed and dry, and must not be made of aluminum, galvanized steel, or other reactive metals.
Potassium Peroxymonosulfate is classified as a non-combustible material but presents significant fire hazard by intensifying combustion of other materials and must be stored segregated from all flammable, combustible, and organic materials in dedicated oxidizer storage facilities.

Chemical Properties of Potassium Peroxymonosulfate:
Potassium Peroxymonosulfate has the molecular formula KHSO₅ (or HKO₅S in PubChem notation), molecular weight 152.17 g/mol, and is the monopotassium salt of peroxymonosulfuric acid (H₂SO₅), containing the HSO₅⁻ (hydrogen peroxomonosulfate) anion with an O-O peroxo bond that is the source of its oxidizing activity; the X-ray crystallographically confirmed structure shows a tetrahedral sulfur center, O-O bond length of 146 pm, and SOOH dihedral angle of 90°.
Potassium Peroxymonosulfate reacts with organic compounds through electrophilic oxygen transfer from the peroxo group, acting as a two-electron oxidant; in the presence of transition metal catalysts it can generate sulfate radical anions (SO₄•⁻) which are powerful one-electron oxidants with redox potential approximately +2.5 to +3.1 V, enabling advanced oxidation of persistent organic compounds.

Potassium Peroxymonosulfate is incompatible with reducing agents (sulfides, sulfites, thiosulfates, ferrous salts), organic materials (acetone, acetic acid, and most organic solvents), combustible materials, metal powders (iron, zinc, aluminum), cyanides, halides (chloride, bromide), reactive metal salts, strong bases, and ammonium compounds; contact with these materials may cause fire, explosion, or violent decomposition.
Potassium Peroxymonosulfate decomposes on heating to potassium sulfate, oxygen, and sulfur dioxide/trioxide; thermal decomposition begins appreciably above approximately 50°C and accelerates with increasing temperature; it must be stored below this temperature and away from heat sources.

Production of Potassium Peroxymonosulfate:
Potassium Peroxymonosulfate (as Oxone triple salt) is produced industrially by the reaction of hydrogen peroxide with sulfuric acid to form peroxymonosulfuric acid (Caro's acid), which is then neutralized with potassium hydroxide or potassium carbonate under controlled conditions to precipitate the potassium peroxymonosulfate product, which is collected, stabilized by combination with potassium hydrogen sulfate and potassium sulfate to form the triple salt, and dried to produce the commercial white crystalline powder.
Potassium Peroxymonosulfate quality is controlled by verification of active oxygen content (by iodometric titration), purity, pH of aqueous solution, appearance, particle size, moisture content, and absence of decomposition products; commercial product is available in technical grade, pool grade, synthesis grade, and electronic grade with varying active oxygen specifications.

Potassium Peroxymonosulfate is available from major chemical suppliers including DuPont (Oxone brand), Evonik, United Initiators, and specialty chemical distributors in 25 kg bags, fiber drums, and bulk containers; storage requires cool (<25°C), dry, well-ventilated dedicated oxidizer storage facilities with dedicated equipment and containers compatible with strong oxidizers (HDPE, PTFE, glass, stainless steel).
Potassium Peroxymonosulfate has a shelf life of approximately 2 years in original sealed containers stored under recommended conditions; active oxygen content should be verified before use in applications where dosing accuracy is critical.
