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.
CATO supplies 2,7-Dimethyl-[1,2,4]triazolo[1,5-a]pyridine (CAS 4931-22-0), a certified reference material (molecular formula C8H9N3, MW 147.18 g/mol) for analytical method development and quality control.
2,7-Dimethyl-[1,2,4]triazolo[1,5-a]pyridine (C8H9N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
