Chemical Structure

2-(4h-1,2,4-Triazol-4-yl)aniline CAS 25660-59-7 chemical structure

Description

2-(4h-1,2,4-Triazol-4-yl)aniline (CAS 25660-59-7), molecular formula C8H8N4 and molecular weight 160.18 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H8N4, 2-(4h-1,2,4-Triazol-4-yl)aniline contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 160.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), 2-(4h-1,2,4-Triazol-4-yl)aniline 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.
