2-Amino-5-chloro-[1,2,4]triazolo[1,5-a]pyridine CAS 175965-64-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Amino-5-chloro-[1,2,4]triazolo[1,5-a]pyridine.

2-Amino-5-chloro-[1,2,4]triazolo[1,5-a]pyridine (CAS 175965-64-7) is a high-purity analytical reference standard with the molecular formula C6H5ClN4 and a molecular weight of 168.58 g/mol.

The molecular framework of 2-Amino-5-chloro-[1,2,4]triazolo[1,5-a]pyridine (C6H5ClN4) is characterized by a nitrile group, chlorine substitution, 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 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.

As a certified reference material (CRM), 2-Amino-5-chloro-[1,2,4]triazolo[1,5-a]pyridine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
