Chemical Structure
Description
The occurrence of 3-Ethyl-7-hydroxy-4,8-dimethyl-2h-chromen-2-one is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-Ethyl-7-hydroxy-4,8-dimethyl-2h-chromen-2-one (CAS 31575-15-2), a certified reference material (molecular formula C13H14O3, MW 218.25 g/mol) for analytical method development and quality control.
The molecular framework of 3-Ethyl-7-hydroxy-4,8-dimethyl-2h-chromen-2-one (C13H14O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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).
