Chemical Structure

1-Phenyl-1H-[1,2,3]triazole, 97% CAS 1453-81-2 chemical structure

Description

As a certified reference material (CRM), 1-Phenyl-1H-[1,2,3]triazole, 97% 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.

1-Phenyl-1H-[1,2,3]triazole, 97% (CAS 1453-81-2), molecular formula C8H7N3 and molecular weight 145.16 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 1-Phenyl-1H-[1,2,3]triazole, 97% is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 145.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
