Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Amino-1H-benzo[d]imidazole-5-carboxylic acid hydrochloride.
2-Amino-1H-benzo[d]imidazole-5-carboxylic acid hydrochloride (CAS 313490-80-1), molecular formula C8H7N3O2HCl and molecular weight 213.62 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Amino-1H-benzo[d]imidazole-5-carboxylic acid hydrochloride (C8H7N3O2HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 213.62 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 2-Amino-1H-benzo[d]imidazole-5-carboxylic acid hydrochloride 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.
