Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,3-Dihydro-7-mercapto-2-oxobenzimidazole-5-carboxylic acid (CAS 548458-12-4) is a high-purity analytical reference standard with the molecular formula C8H4N2O3S and a molecular weight of 208.19 g/mol.
The molecular framework of 2,3-Dihydro-7-mercapto-2-oxobenzimidazole-5-carboxylic acid (C8H4N2O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 2,3-Dihydro-7-mercapto-2-oxobenzimidazole-5-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
