N-(2,4-Difluorophenyl)-1-methyl-3-(trifluoromethyl)-5-({[3-(trifluoromethyl)phenyl]methyl}sulfanyl)-1H-pyrazole-4-carboxamide CAS 321553-24-6

Description

The molecular framework of N-(2,4-Difluorophenyl)-1-methyl-3-(trifluoromethyl)-5-({[3-(trifluoromethyl)phenyl]methyl}sulfanyl)-1H-pyrazole-4-carboxamide (C20H13F8N3OS) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO supplies N-(2,4-Difluorophenyl)-1-methyl-3-(trifluoromethyl)-5-({[3-(trifluoromethyl)phenyl]methyl}sulfanyl)-1H-pyrazole-4-carboxamide (CAS 321553-24-6), a certified reference material (molecular formula C20H13F8N3OS, MW 495.39 g/mol) for analytical method development and quality control.

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.
