5-Chloro-2-Methyl-3-Isothiazolone
5-Chloro-2-Methyl-3-Isothiazolone refers to named chemical substances, formulations or process materials within an identified composition specification.

Product & engineering
Understand the product.
Two of the most widely used isothiazolinone biocides are 5-chloro-2-methyl-4-isothiazolin-3-one (chloromethylisothiazolinone or CMIT) and 2-methyl-4-isothiazolin-3-one (methylisothiazolinone or MIT), which are the active ingredients in a 3:1 mixture (CMIT: MIT) sold commercially as Kathon.
Full identity, composition, supplied form, impurities and compatibility define comparison; application categories do not prove purity, approval or finished-product results.
What turns activity into demand
Purchases need an identified composition or grade, supplied form and accepted specification. Material quantities and purchases of finished equipment are different demand measures; a category label does not establish qualified supply.
The commercial boundary
Use the selected edition’s product level, geography, years and measurement basis. Materials, components, finished systems and services are separate commercial boundaries unless the edition explicitly combines them.
Which composition, supplied form and specification define 5-Chloro-2-Methyl-3-Isothiazolone?
Full identity, composition, supplied form, impurities and compatibility define comparison; application categories do not prove purity, approval or finished-product results.
