Description
CATO manufactures 2,4-Difluoro-N-(4-((phenylthio)methyl)phenyl)benzamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 2,4-Difluoro-N-(4-((phenylthio)methyl)phenyl)benzamide (CAS 321431-82-7), a certified reference material (molecular formula C20H15F2NOS, MW 355.40 g/mol) for analytical method development and quality control.
The molecular framework of 2,4-Difluoro-N-(4-((phenylthio)methyl)phenyl)benzamide (C20H15F2NOS) 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).
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.
