Description

CATO supplies N-(2,4-difluorophenyl)-1,3-dimethyl-5-((3-(trifluoromethyl)phenyl)thio)-1H-pyrazole-4-carboxamide (CAS 303997-98-0), a certified reference material (molecular formula C19H14F5N3OS, MW 427.39 g/mol) for analytical method development and quality control.

The molecular framework of N-(2,4-difluorophenyl)-1,3-dimethyl-5-((3-(trifluoromethyl)phenyl)thio)-1H-pyrazole-4-carboxamide (C19H14F5N3OS) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), N-(2,4-difluorophenyl)-1,3-dimethyl-5-((3-(trifluoromethyl)phenyl)thio)-1H-pyrazole-4-carboxamide 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.
