Benzoisothiazol-3-one（Cat No.:R005361）, also known as 1,2-benzisothiazol-3-one or BIT, is a heterocyclic compound widely used as a preservative and antimicrobial agent in industrial formulations. Its fused benzene and isothiazolone ring structure gives it strong biocidal properties, making it effective against bacteria, fungi, and algae. BIT is commonly found in paints, adhesives, metalworking fluids, and household products to prevent microbial contamination and extend shelf life. It is typically a white to off-white solid, sparingly soluble in water, and functions well in a wide pH range. Careful handling is required due to potential sensitization risks.
