Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-{[4-(4-fluorobenzoyloxy)phenyl]sulfanyl}phenyl 4-fluorobenzoate (CAS 331460-31-2), molecular formula C26H16F2O4S and molecular weight 462.46 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-{[4-(4-fluorobenzoyloxy)phenyl]sulfanyl}phenyl 4-fluorobenzoate (C26H16F2O4S) is characterized by a steroid core, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 4-{[4-(4-fluorobenzoyloxy)phenyl]sulfanyl}phenyl 4-fluorobenzoate 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.
