5-Amino-2-benzimidazolethiol Chemical Properties,Usage,Production

Uses

Compounds with a benzimidazole structure, led by omeprazole, can inhibit the acid secretion of gastric parietal cells induced by any stimulus, thus inhibiting the final step of gastric acid being pumped from the parietal cells into the gastric lumen, and therefore have the best therapeutic effect. 5-Amino-2-mercaptobenzimidazole, as an important starting material or intermediate for this type of drug, has a huge market demand.
