Chemical Structure
Description
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.
5-BRomo-3-methyl[1,2,4]triazolo[4,3-a]pyridine hydrochloride (CAS 1984136-38-0) is a high-purity analytical reference standard with the molecular formula C7H6BrN3HCl and a molecular weight of 248.51 g/mol.
The molecular framework of 5-BRomo-3-methyl[1,2,4]triazolo[4,3-a]pyridine hydrochloride (C7H6BrN3HCl) is characterized by a nitrile group, chlorine/bromine substitution, an aromatic ring system. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
