Chemical Structure

4-(p-Tolyl)-1H-1,2,3-triazole CAS 5301-96-2 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 4-(p-Tolyl)-1H-1,2,3-triazole.

4-(p-Tolyl)-1H-1,2,3-triazole (CAS 5301-96-2), molecular formula C9H9N3 and molecular weight 159.19 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H9N3, 4-(p-Tolyl)-1H-1,2,3-triazole contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 159.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 4-(p-Tolyl)-1H-1,2,3-triazole 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.
