Also known as CMIT, 5-Chloro-2-methyl-4-isothiazolin-3-one, MCI, 2,3-dihydro-2-methyl-3-oxo-5-chloroisothiazole, 5-chloro-2-methyl-2H-isothiazol-3-one
Methylchloroisothiazolinone, also referred to as MCI, is the organic compound with the formula S(C2HCl)C(O)N(CH3). It is a white solid that melts near room temperature. The compound is an isothiazolinone, a class of heterocycles used as biocides. These compounds have an active sulphur moiety that is able to oxidize thiol-containing residues, thereby effectively killing most aerobic and anaerobic bacteria. MCI is often used in combination with methylisothiazolinone, a mixture known as Kathon. The isothiazolinones have attracted attention because they can cause contact dermatitis. Methylchlorois

Methylchloroisothiazolinone is effective against gram-positive and gram-negative bacteria, yeast, and fungi.
== Application == Methylchloroisothiazolinone is found in many water-based personal care products and cosmetics. Methylchloroisothiazolinone was first used in cosmetics in the 1970s. It is also used in glue production, detergents, paints, fuels, and other industrial processes. Methylchloroisothiazolinone is known by the registered tradename Kathon CG when used in combination with methylisothiazolinone.
