Chemical Structure
Description
4,5-Bis(1,3,2-dithiarsolan-2-yl)-9-(4-fluorophenyl)-6-hydroxy-3H-xanthen-3-one (CAS 1378318-62-7), molecular formula C23H17As2FO3S4 and molecular weight 638.48 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4,5-Bis(1,3,2-dithiarsolan-2-yl)-9-(4-fluorophenyl)-6-hydroxy-3H-xanthen-3-one (C23H17As2FO3S4) 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.
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 4,5-Bis(1,3,2-dithiarsolan-2-yl)-9-(4-fluorophenyl)-6-hydroxy-3H-xanthen-3-one 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.
