1-(4-Flourobenzenesulfonyl)-3-(1,3-dioxolynyl)-5-methyl-1,3-dihydro-2H-indol-2-one (CAS 866152-08-1), molecular formula C17H14FNO5S and molecular weight 363.36 g/mol, is a CATO reference standard with documented purity and traceability.
1-(4-Flourobenzenesulfonyl)-3-(1,3-dioxolynyl)-5-methyl-1,3-dihydro-2H-indol-2-one (C17H14FNO5S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 1-(4-Flourobenzenesulfonyl)-3-(1,3-dioxolynyl)-5-methyl-1,3-dihydro-2H-indol-2-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.
