Description

CATO manufactures 8-methyl-[1,2,4]triazolo[4,3-a]pyridine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

8-methyl-[1,2,4]triazolo[4,3-a]pyridine (CAS 4997-81-3) is a high-purity analytical reference standard with the molecular formula C7H7N3 and a molecular weight of 133.15 g/mol.

The molecular framework of 8-methyl-[1,2,4]triazolo[4,3-a]pyridine (C7H7N3) is characterized by a nitrile group, 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. 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.
