Chemical Structure
Description
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.
6-bromo-8-methyl-[1,2,4]triazolo[4,3-a]pyridine (CAS 1216301-85-7), molecular formula C7H14BrN3 and molecular weight 220.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-bromo-8-methyl-[1,2,4]triazolo[4,3-a]pyridine (C7H14BrN3) is characterized by a nitrile group, 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.
