Description
As a certified reference material (CRM), 4-(1,3-Dithiolan-2-yl)phenyl methanesulfonate 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.
4-(1,3-Dithiolan-2-yl)phenyl methanesulfonate (CAS 331461-11-1), molecular formula C10H12O3S3 and molecular weight 276.40 g/mol, is a CATO reference standard with documented purity and traceability.
4-(1,3-Dithiolan-2-yl)phenyl methanesulfonate (C10H12O3S3) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
