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 6-bromo-8-chloro-3-methyl-[1,2,4]triazolo[4,3-a]pyrazine.
6-bromo-8-chloro-3-methyl-[1,2,4]triazolo[4,3-a]pyrazine (CAS 1610045-39-0) is a high-purity analytical reference standard with the molecular formula C6H12BrClN4 and a molecular weight of 255.54 g/mol.
The molecular framework of 6-bromo-8-chloro-3-methyl-[1,2,4]triazolo[4,3-a]pyrazine (C6H12BrClN4) is characterized by a nitrile group, chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
