Chemical Structure
Description
The molecular framework of 6'-[3-(Trifluoromethyl)phenyl]-2,4-dihydrospiro[1-benzopyran-3,3'-[1,5]dioxane]-4-one (C19H15F3O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
6'-[3-(Trifluoromethyl)phenyl]-2,4-dihydrospiro[1-benzopyran-3,3'-[1,5]dioxane]-4-one (CAS 339029-02-6) is a high-purity analytical reference standard with the molecular formula C19H15F3O4 and a molecular weight of 364.32 g/mol.
