Description
CATO manufactures 2-(4-Methoxyphenyl)-5-phenyl-6-(phenylamino)-2,3-dihydro-4H-thiopyran-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.
2-(4-Methoxyphenyl)-5-phenyl-6-(phenylamino)-2,3-dihydro-4H-thiopyran-4-one (CAS 303997-15-1) is a high-purity analytical reference standard with the molecular formula C24H21NO2S and a molecular weight of 387.49 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-(4-Methoxyphenyl)-5-phenyl-6-(phenylamino)-2,3-dihydro-4H-thiopyran-4-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 387.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
