Description

Compared with other compounds in its class, the molecular weight of 301.79 g/mol gives 4-(4-chlorophenyl)-5-(4-methylphenyl)-4H-1,2,4-triazole-3-thiol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-(4-chlorophenyl)-5-(4-methylphenyl)-4H-1,2,4-triazole-3-thiol (CAS 451501-95-4), a certified reference material (molecular formula C15H12ClN3S, MW 301.79 g/mol) for analytical method development and quality control.

4-(4-chlorophenyl)-5-(4-methylphenyl)-4H-1,2,4-triazole-3-thiol (C15H12ClN3S) 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.

As a certified reference material (CRM), 4-(4-chlorophenyl)-5-(4-methylphenyl)-4H-1,2,4-triazole-3-thiol 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.
