4-Methyl-2-(1h-1,2,4-triazol-3-yl)aniline CAS 1249505-23-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Methyl-2-(1h-1,2,4-triazol-3-yl)aniline.

4-Methyl-2-(1h-1,2,4-triazol-3-yl)aniline (CAS 1249505-23-4) is a high-purity analytical reference standard with the molecular formula C9H10N4 and a molecular weight of 174.20 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 4-Methyl-2-(1h-1,2,4-triazol-3-yl)aniline is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 174.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
