As a certified reference material (CRM), 4-Aminobenzimidamide 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.
4-Aminobenzimidamide hydrochloride (CAS 7761-72-0) is a high-purity analytical reference standard with the molecular formula C7H9N3HCl and a molecular weight of 171.63 g/mol.
4-Aminobenzimidamide hydrochloride (C7H9N3HCl) contains a nitrile group, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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.
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.
