4-(5-Amino-1H-benzo[d]imidazol-2-yl)benzoic acid dihydrochloride CAS 1158534-13-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(5-Amino-1H-benzo[d]imidazol-2-yl)benzoic acid dihydrochloride.

4-(5-Amino-1H-benzo[d]imidazol-2-yl)benzoic acid dihydrochloride (CAS 1158534-13-4), molecular formula C14H11N3O2HCl and molecular weight 289.72 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 4-(5-Amino-1H-benzo[d]imidazol-2-yl)benzoic acid dihydrochloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 289.72 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 4-(5-Amino-1H-benzo[d]imidazol-2-yl)benzoic acid dihydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
