Chemical Structure
Description
The molecular framework of N-(2,4-difluorophenyl)-6-methoxy-2H-chromene-3-carboxamide (C17H13F2NO3) is characterized by a steroid core, an amide group, 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).
N-(2,4-difluorophenyl)-6-methoxy-2H-chromene-3-carboxamide (CAS 338760-46-6) is a high-purity analytical reference standard with the molecular formula C17H13F2NO3 and a molecular weight of 317.29 g/mol.
