Metabolite Identification
Common Name2-Ethylbenzothiazole
Description2-Ethylbenzothiazole 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). Based on a literature review very few articles have been published on 2-Ethylbenzothiazole.
