The molecular framework of N-(2,4-Difluorophenyl)-1-methyl-3-(trifluoromethyl)-5-{[3-(trifluoromethyl)phenyl]sulfanyl}-1H-pyrazole-4-carboxamide (C19H11F8N3OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
N-(2,4-Difluorophenyl)-1-methyl-3-(trifluoromethyl)-5-{[3-(trifluoromethyl)phenyl]sulfanyl}-1H-pyrazole-4-carboxamide (CAS 400086-42-2), molecular formula C19H11F8N3OS and molecular weight 481.36 g/mol, is a CATO reference standard with documented purity and traceability.
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.
