Chemical Structure

2-Thioxo-2,3-dihydro-1H-benzimidazole-5-carboxylic acid 2-thioxo-2,3-dihydro-1H-benzo[d]imidazole-5-carboxylic acid 58089-25-1 CAS 58089-25-1 chemical structure

Description

The molecular framework of 2-Thioxo-2,3-dihydro-1H-benzimidazole-5-carboxylic acid 2-thioxo-2,3-dihydro-1H-benzo[d]imidazole-5-carboxylic acid 58089-25-1 (C8H14N2O2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
