Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Methyl-4,5-dihydro-1H-imidazol-2-amine hydrobromide.
1-Methyl-4,5-dihydro-1H-imidazol-2-amine hydrobromide (CAS 34122-57-1) is a high-purity analytical reference standard with the molecular formula C4H9N3HBr and a molecular weight of 180.05 g/mol.
Structurally, 1-Methyl-4,5-dihydro-1H-imidazol-2-amine hydrobromide (C4H9N3HBr) contains bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 180.05 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), 1-Methyl-4,5-dihydro-1H-imidazol-2-amine hydrobromide 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.
