Mercaptobenzothiazole - Wikipedia

2-Mercaptobenzothiazole is an organosulfur compound with the formula C6H4(NH)SC=S. A white solid, it is used in the sulfur vulcanization of rubber. [1] Structure [ edit] The molecule is planar with a C=S double bond, so the name mercapto benzothiazole is a misnomer.
