MERGAL K14 (sometimes isothiazolone) is a heterocyclic chemical compound related to isothiazole.
Compared to many other simple heterocycles MERGAL K14 discovery is fairly recent, with reports first appearing in the 1960s.
MERGAL K14 itself has no applications, however MERGAL K14 derivatives are widely used as biocides.
Properties of MERGAL K14:
MERGAL K14 demonstrates improved performance and improved activity over conventional isothiazolinone bactericides.
MERGAL K14 provides improved sanitation speed and greater resilience to re-invasion of microorganisms.
MERGAL K14 is more robust in these challenging conditions and retains more sanitary strength where conventional CMIT / MIT products experience severe loss of activity.
In some markets and for some applications, low levels of chloromethyl isothiazolinone (15-30 ppm) are desirable.
MERGAL K14 is an excellent choice for these applications as MERGAL K14 is a synergistic combination of preservatives (just a small portion of a formulation such as CMIT).
MERGAL K14 has a wide range of activity against bacteria, yeast and some algae.

Uses Area of MERGAL K14:
MERGAL K14 is often not stable under certain conditions such as high temperatures or high pH values.
Normally MERGAL K14 is stabilised with Mg, Cu or Na salts.
However, some applications are sensitive to salts or electrolyte.
In this case Exocide 1012 AG is an excellent alternative.
This broadband biocide is used to preserve water-based and water-dilutable chemical/technical products, and can be used as an in-can preservative in technical applications such as paints, adhesives, and household and industrial cleaners.
MERGAL K14 is especially suitable for preserving fuels such as diesel, or for use in secondary oil production.
This Exocide is also suitable as a slimicide, protective media for liquids in cooling and production systems, and as a protective medium for fluids used in metalworking.
This biocide formulation has a broad antimicrobial spectrum of activity against bacteria, fungi and yeasts and can be used in many cases where other products fail.
Application of MERGAL K14:
MERGAL K14 is a liquid product that can be easily incorporated into aqueous systems.
MERGAL K14 can be used in adhesives that can come into direct or indirect contact with food, as a component of paper and cardboard in contact with aqueous, dry and fatty products, and in pigment pastes.
MERGAL K14s are antimicrobials used to control bacteria, fungi, and algae in cooling water systems, fuel storage tanks, pulp and paper mill water systems, oil extraction systems, wood preservation and antifouling agents.
They are frequently used in personal care products such as shampoos and other hair care products, as well as certain paint formulations.
Often, combinations of MIT and CMIT (known as Kathon CG) or MIT and BIT are used.
Cleaners and polishes, such as all-purpose cleaners, cleaning and industrial use wipes, floor and furniture polishes/waxes, automotive washes, polishes and waxes,
Laundry products, such as liquid laundry detergents, fabric softeners and pre-spotters,
Liquid detergents, such as dish wash detergents and general liquid cleaning solution,
Other applications, such as moist towelettes, air fresheners, moist sponges, gel air fresheners,
Raw materials and surfactants preservation.
Chloromethyl-methylMERGAL K14 (MERGAL K14) is a broad spectrum biocide which has been used successfully for microbial control and preventing biofouling in industrial water treatment.
The studies included a wide range of conditions, including single organisms in cooling water and complex model systems with bacteria, biofilms, and protozoa.
Overall, low levels of MERGAL K14 (1-10 ppm active) provided significant reduction in viable counts of various strains and species of Legionella bacteria in planktonic and biofilm studies and also against the amoebae and ciliated protozoa associated with their growth.
MERGAL K14 Biocides In Water Treatment:
MERGAL K14 biocides are widely used for microbial control in industrial water treatment.
The most frequently used product is a 3:1 ratio of 5-chloro-2-methyl-4-isothiazolin-3-one (CMIT) and 2-methyl- 4-isothiazolin-3-one (MIT) at a final concentration of 1.5% total active ingredient.
MERGAL K14 has broad spectrum efficacy versus bacteria, algae, and fungi.
Exocide product is a blend of Isothiazolinones and is composed of 5-chloro-2-methyl-4-thiazoline-3-ketone (CMIT) and 2-methyl-4-thiazoline-3-ketone (MIT).
The bactericidal effect of Isothiazolinones is carried out through breaking the bond between the bacteria and algae protein.
MERGAL K14 can be used in many industrial applications to inhibit microbes’ growth, and MERGAL K14 has inhibition and biocidal effects on ordinary bacteria, fungi and algae.
Isothiazolinones (also MERGAL K14) is a blended biocide with MERGAL K14 and Isothiazolinone which carry out the bactericidal effect through breaking the bond of bacteria and algae cell protein.
When isothiazolinones contact with microbes, MERGAL K14 can quickly break cell protein bond and inhibit their growth, and then lead to the apoptosis of these microbes.
Isothiazolinone products can be effective in controlling both the planktonic and surface growth at very low concentrations and have been produced specifically for oilfield water treatment and paper mill applications.
MERGAL K14 has strong biocidal effects on ordinary bacteria, algae and fungi which has many advantages such as no residue, good compatibleness, high stabilization, good degradation, safety and low cost in operation.
Isothiazolinone products can mix with other chlorine biocides and most cation, anion, and non-ionic surfactants.
MERGAL K14 can be an excellent eco-friendly sludge remover when used at high dosage.
MERGAL K14 and Isothiazolinone are fungicidal with properties of high efficiency, broad spectrum, non-oxidative and low toxicity.
MERGAL K14 is the most suitable biocide in industrial circulating cool water systems and in wastewater treatment for oilfield, papermaking, pesticide and other industries.
Bichain is one of reliable isothiazolinones manufacturers and suppliers of MERGAL K14, CMIT and MIT for oilfield water treatment.
We supply high quality isothiazolinone products with CAS 55965-84-9.

Synthesis of MERGAL K14:
Various synthetic routes have been reported.
MERGAL K14s are typically prepared on an industrial scale by the ring-closure of 3-sulfanylpropanamide derivatives.
Yhese in turn are produced from acrylic acid via the 3-mercaptopropionic acid.
Ring-closure involves conversion of the thiol group into a reactive species which undergoes nucleophilic attack by the nitrogen center.
This typically involves chlorination, or oxidation of the 3-sulfanylpropanamide to the corresponding disulfide species.
These reaction conditions also oxidize the intermediate isothiazolidine ring to give the desire product.
