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.

General description

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