Chemical Structure

4-(5-(m-Tolyl)-1H-1,2,4-triazol-3-yl)aniline CAS 1049139-25-4 chemical structure

Description

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.

4-(5-(m-Tolyl)-1H-1,2,4-triazol-3-yl)aniline (CAS 1049139-25-4) is a high-purity analytical reference standard with the molecular formula C15H14N4 and a molecular weight of 250.30 g/mol.

The molecular framework of 4-(5-(m-Tolyl)-1H-1,2,4-triazol-3-yl)aniline (C15H14N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 4-(5-(m-Tolyl)-1H-1,2,4-triazol-3-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.
