3-{[(2-chlorophenyl)methyl]sulfanyl}-5-(thiophen-2-yl)-4H-1,2,4-triazol-4-amine CAS 477872-63-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-{[(2-chlorophenyl)methyl]sulfanyl}-5-(thiophen-2-yl)-4H-1,2,4-triazol-4-amine.

3-{[(2-chlorophenyl)methyl]sulfanyl}-5-(thiophen-2-yl)-4H-1,2,4-triazol-4-amine (CAS 477872-63-2) is a high-purity analytical reference standard with the molecular formula C13H11ClN4S2 and a molecular weight of 322.84 g/mol.

The molecular framework of 3-{[(2-chlorophenyl)methyl]sulfanyl}-5-(thiophen-2-yl)-4H-1,2,4-triazol-4-amine (C13H11ClN4S2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
