Isothiazolinone (/ˌaɪsoʊˌθaɪ.əˈzoʊlɪnoʊn/; sometimes isothiazolone) is an organic compound with the formula (CH)₂SN(H)CO. A white solid, it is structurally related to isothiazole. Isothiazolone itself is of limited interest, but several of its derivatives are widely used preservatives and antimicrobials.
