Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-Bromo-2-methyl-3H-imidazo[4,5-b]pyridine.
7-Bromo-2-methyl-3H-imidazo[4,5-b]pyridine (CAS 1392102-13-4), molecular formula C7H6BrN3 and molecular weight 212.05 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, bromine substitution, an aromatic ring system, 7-Bromo-2-methyl-3H-imidazo[4,5-b]pyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 212.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 7-Bromo-2-methyl-3H-imidazo[4,5-b]pyridine 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.
