Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-[(1H-imidazol-1-yl)amino]benzoic acid hydrochloride (CAS 1989671-35-3) is a high-purity analytical reference standard with the molecular formula C10H9N3O2HCl and a molecular weight of 239.66 g/mol.
4-[(1H-imidazol-1-yl)amino]benzoic acid hydrochloride (C10H9N3O2HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 4-[(1H-imidazol-1-yl)amino]benzoic 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.
