2-(5-Hydroxy-4-methyl-3-phenyl-4,5-dihydroisoxazol-5-yl)benzoic acid (CAS 63826-30-2), molecular formula C17H15NO4 and molecular weight 297.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(5-Hydroxy-4-methyl-3-phenyl-4,5-dihydroisoxazol-5-yl)benzoic acid (C17H15NO4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
