Metabolite Identification
Common Name2(3H)-Benzothiazolethione
Description2(3H)-Benzothiazolethione, also known as captax or 2-mercaptobenzothiazole, 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). 2(3H)-Benzothiazolethione is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, 2(3H)-Benzothiazolethione has been detected, but not quantified in, fruits. This could make 2(3H)-benzothiazolethione a potential biomarker for the consumption of these foods. 2(3H)-Benzothiazolethione is a potentially toxic compound. 1,3-Benzothiazole substituted at the 2-position with a sulfanyl group.
