2-Mercapto-5-methoxybenzimidazole is used in the preparation of COX-2 inhibitors. It is also employed in the preparation of compounds such as 5-methoxy-2[[(4-methoxy-3, 5-dimethyl-2-pyridinyl) methyl] sulfonyl]-1H-benzimidazole, 5-methoxy-2[[(4-methoxy-3, 5-dimethylpyridin-2-yl-1-oxide) methyl] sulfonyl]-1H-benzimidazole as well as tris[μ-1,2-bis(diphenylphosphino)ethane]-1:2κ2P:P′;1:3κ2P:P′;2:3κ2P:P′-di-μ-bromido-1:2κ4Br:Br-bromido-3κBr-tricopper(I) acetone hemisolvate. Furthermore, it acts as a hetercocyclic building block and serves as an intermediate of drug omeprazole1. Finally, it acts as an intermediate for manufacture of the anti-ulcer drug Omeprazole.
