Chemical Structure
Description
As a certified reference material (CRM), 6-bromo-2-methyl-[1,2,4]triazolo[4,3-a]pyridin-3-one 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.
6-bromo-2-methyl-[1,2,4]triazolo[4,3-a]pyridin-3-one (CAS 1782729-97-8), molecular formula C7H12BrN3O and molecular weight 234.09 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-bromo-2-methyl-[1,2,4]triazolo[4,3-a]pyridin-3-one (C7H12BrN3O) is characterized by an amide group, a hydroxyl group, an ether linkage, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
