Sodium 2-mercapto-1H-benzo[d]imidazole-5-sulfonate CAS 53918-03-9

Description

The occurrence of Sodium 2-mercapto-1H-benzo[d]imidazole-5-sulfonate is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Sodium 2-mercapto-1H-benzo[d]imidazole-5-sulfonate (CAS 53918-03-9) is a high-purity analytical reference standard with the molecular formula C7H5N2O3S2Na and a molecular weight of 252.24 g/mol.

The molecular framework of Sodium 2-mercapto-1H-benzo[d]imidazole-5-sulfonate (C7H5N2O3S2Na) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
