93752-78-4 Avenacein Y 4H,6H-Benzo(1,2-b:4,5-c')dipyran-8-carboxylic acid, 5-hydroxy-9-methoxy-2-methyl-4,6-dioxo- (CAS 93752-78-4) is a high-purity analytical reference standard with the molecular formula C15H10O8 and a molecular weight of 318.24 g/mol.
The molecular framework of 93752-78-4 Avenacein Y 4H,6H-Benzo(1,2-b:4,5-c')dipyran-8-carboxylic acid, 5-hydroxy-9-methoxy-2-methyl-4,6-dioxo- (C15H10O8) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
