Description
CATO manufactures 2,3-Dihydro-7-methoxy-4H-1-benzothiopyran-4-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.
CATO supplies 2,3-Dihydro-7-methoxy-4H-1-benzothiopyran-4-one (CAS 13851-03-1), a certified reference material (molecular formula C10H10O2S, MW 194.25 g/mol) for analytical method development and quality control.
2,3-Dihydro-7-methoxy-4H-1-benzothiopyran-4-one (C10H10O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
