Allgemeine Beschreibung

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

Anwendung

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.

2-Mercaptobenzimidazole (MBI), a rubber antioxidant, is known to exhibit potent thyroid toxicity in rats, whereas its methylated derivatives are much less toxic. To characterize this methyl-substituent effect on the thyroid toxicity of MBI, comparative toxicokinetic analyses have been conducted in

In the present study, surface-enhanced Raman spectra of a bifunctional Raman reporter, 2-mercaptobenzimidazole, has been found to be responsive exclusively towards Cu(2+) ions while the reporter remains anchored on the Au nanoparticle surface. Thus a specific Cu(2+)-ion-detection protocol emerges. The
