5-Chloro-2-methyl-4-isothiazoline-3-one (CMIT/MCI) is the active biocide component in the widely used Kathon™-type preservative systems, providing broad-spectrum antimicrobial activity at very low concentrations. It is used in combination with MIT (methylisothiazolinone) as a cost-effective preservative in industrial water treatment, paints, and personal care products.
