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-Phenyl-2-(phenylsulfonyl)ethan-1-one (CAS 3406-03-9), molecular formula C14H12O3S and molecular weight 260.31 g/mol, is a CATO reference standard with documented purity and traceability.
1-Phenyl-2-(phenylsulfonyl)ethan-1-one (C14H12O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 1-Phenyl-2-(phenylsulfonyl)ethan-1-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
