Description

CATO supplies 1-[(2,4-Dichlorophenyl)methyl]-3-[4-(prop-2-en-1-yl)-5-({[4-(trifluoromethyl)phenyl]methyl}sulfanyl)-4H-1,2,4-triazol-3-yl]-1,2-dihydropyridin-2-one (CAS 400074-88-6), a certified reference material (molecular formula C25H19Cl2F3N4OS, MW 551.41 g/mol) for analytical method development and quality control.

1-[(2,4-Dichlorophenyl)methyl]-3-[4-(prop-2-en-1-yl)-5-({[4-(trifluoromethyl)phenyl]methyl}sulfanyl)-4H-1,2,4-triazol-3-yl]-1,2-dihydropyridin-2-one (C25H19Cl2F3N4OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; 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), 1-[(2,4-Dichlorophenyl)methyl]-3-[4-(prop-2-en-1-yl)-5-({[4-(trifluoromethyl)phenyl]methyl}sulfanyl)-4H-1,2,4-triazol-3-yl]-1,2-dihydropyridin-2-one 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.
