4-[[(2,3-Dihydro-2-oxo-1H-benzimidazol-5-yl)sulfonyl]amino]benzoic acid CAS 726155-15-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-[[(2,3-Dihydro-2-oxo-1H-benzimidazol-5-yl)sulfonyl]amino]benzoic acid.

CATO supplies 4-[[(2,3-Dihydro-2-oxo-1H-benzimidazol-5-yl)sulfonyl]amino]benzoic acid (CAS 726155-15-3), a certified reference material (molecular formula C14H11N3O5S, MW 333.32 g/mol) for analytical method development and quality control.

Structurally, 4-[[(2,3-Dihydro-2-oxo-1H-benzimidazol-5-yl)sulfonyl]amino]benzoic acid (C14H11N3O5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 333.32 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
