Chemical Structure

1-((4-Nitrophenyl)sulfonyl)-1h-benzo[d]imidazole CAS 1091-57-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 303.29 g/mol gives 1-((4-Nitrophenyl)sulfonyl)-1h-benzo[d]imidazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-((4-Nitrophenyl)sulfonyl)-1h-benzo[d]imidazole (CAS 1091-57-2), a certified reference material (molecular formula C13H9N3O4S, MW 303.29 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 1-((4-Nitrophenyl)sulfonyl)-1h-benzo[d]imidazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 303.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
