2-甲基异噻唑-3-酮/5-氯-2-甲基异噻唑-3-酮(1:1) (CAS No.55965-84-9)

Product Name:Mixture of 5-chloro-2-methylisothiazol-3-one and 2-methylisothiazol-3-one (1:1)

English Name:Mixture of 5-chloro-2-methylisothiazol-3-one and 2-methylisothiazol-3-one (1:1)

CAS No.:55965-84-9

Aliases:CMIT/MIT mixture, Kathon, Isothiazolinone biocide

Molecular Formula:C4H4ClNOS + C4H5NOS

Physical Properties:Light yellow to amber transparent liquid with a slight characteristic odor. Readily soluble in water, lower alcohols and ethylene glycol; difficult to dissolve in non-polar organic solvents. Relative density (20°C): approximately 1.02-1.05 g/cm³; pH (1% aqueous solution): approximately 3.0-5.0. Exhibits broad-spectrum antimicrobial activity with inhibitory effects against bacteria, fungi and algae. Good stability, but readily decomposes under alkaline conditions or at high temperatures.

Uses:Widely used as a preservative and biocide in aqueous systems such as coatings, emulsions, adhesives, papermaking, water treatment, and personal care products. Effectively inhibits the growth of bacteria, fungi and algae, extending product shelf life. Exhibits highly effective biocidal action even at low concentrations.
