(E)-3-((5-fluoro-2-methylphenyl)amino)-1-(3-(3-methoxyphenyl)benzo[c]isoxazol-5-yl)prop-2-en-1-one (CAS 383147-20-4), molecular formula C24H19FN2O3 and molecular weight 402.42 g/mol, is a CATO reference standard with documented purity and traceability.
(E)-3-((5-fluoro-2-methylphenyl)amino)-1-(3-(3-methoxyphenyl)benzo[c]isoxazol-5-yl)prop-2-en-1-one (C24H19FN2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures (E)-3-((5-fluoro-2-methylphenyl)amino)-1-(3-(3-methoxyphenyl)benzo[c]isoxazol-5-yl)prop-2-en-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.
