Description

General description

2-Mercaptobenzimidazole is a good corrosion inhibitor as it reduces the corrosion rate of metals.

Application

2-Mercaptobenzimidazole can be used:

To prepare 2-benzimidazolylthioacetophenones by reacting with aromatic ketones, which is a key intermediate for the synthesis of thiazolo[3,2-a]benzimidazoles.
To synthesize S-arylated 2-mercapto-benzimidazoles via S-arylation with substituted aryl iodides using CuI and 1,10-phenanthroline.

Structural and mechanistic aspects of transcriptional induction of cytochrome P450 1A1 by benzimidazole derivatives in rat hepatoma H4IIE cells.

M Backlund et al.

European journal of biochemistry, 261(1), 66-71 (1999-04-02)

The effect of several structurally different benzimidazole compounds on CYP1A1 expression at the transcriptional, mRNA and protein levels was investigated in the rat hepatoma H4IIE cell line. Omeprazole, thiabendazole, carbendazim, 2-mercaptobenzimidazole and 2-mercapto-5-methoxybenzimidazole caused a dose-dependent increase in CYP1A1 protein

Simultaneous spectrophotometric determination of 2-thiouracil and 2-mercaptobenzimidazole in animal tissue using multivariate calibration methods: concerns and rapid methods for detection.

Abolghasem Beheshti et al.

Journal of food science, 75(2), C135-C139 (2010-05-25)

Two multivariate calibration methods, partial least squares (PLS) and principal component regression (PCR), were applied to the spectrophotometric simultaneous determination of 2-mercaptobenzimidazole (MB) and 2-thiouracil (TU). A genetic algorithm (GA) using partial least squares was successfully utilized as a variable
