Chemical Structure
Description
4-((4-Fluorophenyl)sulfonyl)-5-((1-phenylethyl)thio)-2-(thiophen-2-yl)oxazole (CAS 850927-93-4), molecular formula C21H16FNO3S3 and molecular weight 445.55 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-((4-Fluorophenyl)sulfonyl)-5-((1-phenylethyl)thio)-2-(thiophen-2-yl)oxazole (C21H16FNO3S3) is characterized by a steroid core, an amide group, a sulfone group, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4-((4-Fluorophenyl)sulfonyl)-5-((1-phenylethyl)thio)-2-(thiophen-2-yl)oxazole 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.
