Metabolite Identification
Common Name1,2-Benzisothiazol-3(2H)-one
Description1,2-Benzisothiazol-3(2H)-one, also known as benzisothiazolone or proxel, belongs to the class of organic compounds known as benzothiazoles. These are organic compounds containing a benzene fused to a thiazole ring (a five-membered ring with four carbon atoms, one nitrogen atom and one sulfur atom). 1,2-Benzisothiazol-3(2H)-one exists as a solid, slightly soluble (in water), and a very weakly acidic compound (based on its pKa). Within the cell, 1,2-benzisothiazol-3(2H)-one is primarily located in the cytoplasm. 1,2-Benzisothiazol-3(2H)-one is a potentially toxic compound.
