Description

Compared with other compounds in its class, the molecular weight of 124.14 g/mol gives 1H,4H,5H,6H,7H-[1,2,3]triazolo[4,5-b]pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1H,4H,5H,6H,7H-[1,2,3]triazolo[4,5-b]pyridine (CAS 1125405-40-4) is a high-purity analytical reference standard with the molecular formula C5H8N4 and a molecular weight of 124.14 g/mol.

The molecular framework of 1H,4H,5H,6H,7H-[1,2,3]triazolo[4,5-b]pyridine (C5H8N4) is characterized by a nitrile group. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 1H,4H,5H,6H,7H-[1,2,3]triazolo[4,5-b]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.
