chemical research in toxicology, 20 (8), 1084-1092 (2007-07-17) the rubber accelerator, 2-mercaptobenzothiazole (mbt), has been reported to cause allergic contact dermatitis from gloves and other rubber products, but its chemical fate when exposed to occupational oxidants and the mechanism of its pathogenesis are not known. it was hypothesized.

2 mercaptobenzothiazole - an overview sciencedirect topics.2-mbt is used as a vulcanization accelerator especially in rubber products like car tires, cables, seals, shoes, rubber gloves and toys (baua, 2001; bfr, 2008). therefore, a general possible exposure of the population to 2-mbt can be supposed. fukuoka and tanaka suggested the metabolism pattern in rats (fukuoka et al., 1995).

tautomers and deprotonated form of mercaptobenzothiazole the molecule is planar with a c=s double bond, so the name mercaptobenzothiazole is a misnomer, a more appropriate name could be benzothiazoline-2-thione.solution measurements by nmr spectroscopy could not measure the presence of the thiol tautomer that the name implies, instead it exists as a thione/dithiocarbamate and the hydrogen.
