Description
Phenolsulfonic acid is a stable, clear, pale yellow mobile liquid.
Phenolsulfonic acid is soluble and miscible with carbon tetrachloride, dioxane, vegetable oils, xylene, alcohols, ethers, and esters.
Phenolsulfonic acid get hydrolysed in the presence of moisture and by alkalis, toxic oxides of carbon, sulphur, and phosphorus.
Phenolsulfonic acid may be used in foliar or soil treatments on alfalfa, barley, beans, brassicas, coffee, corn, cotton, grapes, hops, lettuce, oats, peanuts, potatoes, rice, sorghum, soybeans, sugarcane, sugar beets, tomatoes, watermelon, wheat, and on ornamentals and pine nursery stock.
Phenolsulfonic acid has applications for the control of a wide variety of crop pests such as mites, aphids, greenbugs, thrips, leafhoppers, sorghum shoot fly, leaf miners, corn rootworms, psyllids, cutworms, Hessian fly, foliar nematodes, wireworms, flea beetles, whiteflies, pine tip moth, and others.
A yellowish liquid that becomes brown on exposure to air.
Phenolsulfonic acid is soluble in alcohol.
Irritating to mucous membranes, skin, and eyes.
Moderately toxic by ingestion.
Used as a laboratory reagent, in water analysis and in the manufacture of pharmaceuticals.
A mixture of ortho and para isomers.
Phenolsulfonic acid has a variety of applications, such as metal working and processing, Phenolsulfonic acid is used as polymerization catalyst, chemical intermediate, textile dye manufacturing, as well as oilfield chemicals.
Phenolsulfonic acid is used in endodontic therapy for disinfection.

EPA Substance Registry System: Phenolsulfonic acid (1333-39-7)
Phenolsulfonic acid is a mixture of ortho and para isomers.
Phenolsulfonic acid is a yellow-coloured liquid and on exposure to air turns brown in colour.
Phenolsulfonic acid is soluble in alcohol and is used as a laboratory reagent, in water analysis and in the manufacture of pharmaceuticals.
Phenolsulfonic acid is a combustible material, but does not ignite readily.
On heating, Phenolsulfonic acid emits vapours, which may form explosive mixtures with air and cause explosion hazards.
Also, on contact with metals, Phenolsulfonic acid emits flammable hydrogen gas and the containers cause explosion.
Phenolsulfonic acid reacts exothermically with chemical bases, for example, amines and inorganic hydroxides to form salts.
Phenolsulfonic acid, liquid appears as a yellowish liquid that becomes brown on exposure to air.
Soluble in alcohol.
Irritating to mucous membranes, skin, and eyes.
Moderately toxic by ingestion.
Used as a laboratory reagent, in water analysis and in the manufacture of pharmaceuticals.
A mixture of ortho and para isomers.
Reactivity Profile
Phenolsulfonic acid is a strong acid.
Reacts exothermically with chemical bases (for example: amines and inorganic hydroxides) to form salts.
Dissolution in water or the dilution of a concentrated solutions with water may generate significant amounts of heat.
Can serve as an oxidizing agent, but has a much weaker oxidizing action than sulfuric acid [Noller].
Can react with active metals, including iron and aluminum, and also many less active metals, to dissolve the metal and liberate hydrogen and/or toxic gases.
Can initiate polymerization in certain classes of organic compounds.
Reactions with cyanide salts and compounds release gaseous hydrogen cyanide.
Flammable and/or toxic gases may be generated by reactions with dithiocarbamates, isocyanates, mercaptans, nitrides, nitriles, sulfides, and strong reducing agents.
Additional gas-generating reactions occur with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), and even carbonates: the carbon dioxide gas from the last is nontoxic but the heat and spattering from the reaction can be troublesome.
Can catalyze (increase the rate) of chemical reactions.
