Chemical Structure

8-Methyl-[1,2,4]triazolo[1,5-a]pyridine CAS 4931-18-4 chemical structure

Description

8-Methyl-[1,2,4]triazolo[1,5-a]pyridine (CAS 4931-18-4) is a high-purity analytical reference standard with the molecular formula C7H7N3 and a molecular weight of 133.15 g/mol.

8-Methyl-[1,2,4]triazolo[1,5-a]pyridine (C7H7N3) contains a nitrile group, an aromatic ring system. 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).

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.
