3-{[(3-chlorophenyl)methyl]sulfanyl}-5-(thiophen-2-yl)-4H-1,2,4-triazol-4-amine CAS 477872-64-3

Description

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

CATO supplies 3-{[(3-chlorophenyl)methyl]sulfanyl}-5-(thiophen-2-yl)-4H-1,2,4-triazol-4-amine (CAS 477872-64-3), a certified reference material (molecular formula C13H11ClN4S2, MW 322.84 g/mol) for analytical method development and quality control.

3-{[(3-chlorophenyl)methyl]sulfanyl}-5-(thiophen-2-yl)-4H-1,2,4-triazol-4-amine (C13H11ClN4S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
