CATO supplies 4-(2,4-Dipropoxybenzylidene)-1-phenylpyrazolidine-3,5-dione (CAS 820237-41-0), a certified reference material (molecular formula C22H24N2O4, MW 380.44 g/mol) for analytical method development and quality control.
The molecular framework of 4-(2,4-Dipropoxybenzylidene)-1-phenylpyrazolidine-3,5-dione (C22H24N2O4) 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.
