Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Bromoimidazo[1,2-b][1,2,4]triazine.
2-Bromoimidazo[1,2-b][1,2,4]triazine (CAS 1546562-70-2) is a high-purity analytical reference standard with the molecular formula C5H3BrN4 and a molecular weight of 199.01 g/mol.
Owing to a nitrile group, bromine substitution, 2-Bromoimidazo[1,2-b][1,2,4]triazine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 199.01 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
