Quick Summary

Mercaptobenzothiazole (MBT) is a crystalline heterocyclic compound with the chemical formula C₇H₄NS(SH). It is derived from benzothiazole, which is a liquid compound made from ortho-amino-thiophenol and formaldehyde.12

MBT is primarily used as an accelerator in the vulcanization of rubber and also functions as a corrosion inhibitor. It is synthesized by heating aniline, sulfur, and carbon disulfide.341
