2-((4-Chlorophenyl)sulfonyl)-1-(4-methoxyphenyl)ethan-1-one (CAS 61820-97-1) is a high-purity analytical reference standard with the molecular formula C15H13ClO4S and a molecular weight of 324.78 g/mol.
2-((4-Chlorophenyl)sulfonyl)-1-(4-methoxyphenyl)ethan-1-one (C15H13ClO4S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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.
CATO manufactures 2-((4-Chlorophenyl)sulfonyl)-1-(4-methoxyphenyl)ethan-1-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.
