Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(4-Chlorophenyl)-5-((4-methylbenzyl)thio)-4-(p-tolyl)-4H-1,2,4-triazole.
CATO supplies 3-(4-Chlorophenyl)-5-((4-methylbenzyl)thio)-4-(p-tolyl)-4H-1,2,4-triazole (CAS 477332-97-1), a certified reference material (molecular formula C23H20ClN3S, MW 405.94 g/mol) for analytical method development and quality control.
3-(4-Chlorophenyl)-5-((4-methylbenzyl)thio)-4-(p-tolyl)-4H-1,2,4-triazole (C23H20ClN3S) 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. 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.
As a certified reference material (CRM), 3-(4-Chlorophenyl)-5-((4-methylbenzyl)thio)-4-(p-tolyl)-4H-1,2,4-triazole 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.
