5-(4-Chlorophenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-amine CAS 1369374-16-2

Description

The occurrence of 5-(4-Chlorophenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-amine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-(4-Chlorophenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-amine (CAS 1369374-16-2), molecular formula C12H9ClN4 and molecular weight 244.68 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 5-(4-Chlorophenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-amine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 244.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
