Chemical Structure
Description
2,8-Dimethyl-[1,2,4]triazolo[1,5-a]pyridine (CAS 4931-19-5), molecular formula C8H9N3 and molecular weight 147.18 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2,8-Dimethyl-[1,2,4]triazolo[1,5-a]pyridine (C8H9N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 147.18 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 manufactures 2,8-Dimethyl-[1,2,4]triazolo[1,5-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.
