Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-(4-Methanesulfonyl-phenyl)-2-phenyl-ethane-1,2-dione (CAS 54945-18-5), molecular formula C15H12O4S and molecular weight 288.32 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(4-Methanesulfonyl-phenyl)-2-phenyl-ethane-1,2-dione (C15H12O4S) is characterized by a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. 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).
CATO manufactures 1-(4-Methanesulfonyl-phenyl)-2-phenyl-ethane-1,2-dione 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.
