Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2,4-Difluoro-N-(4-(((4-fluorophenyl)thio)methyl)phenyl)benzamide (CAS 338398-76-8), a certified reference material (molecular formula C20H14F3NOS, MW 373.39 g/mol) for analytical method development and quality control.
The molecular framework of 2,4-Difluoro-N-(4-(((4-fluorophenyl)thio)methyl)phenyl)benzamide (C20H14F3NOS) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
