7-Ethoxy-4-methyl-2H-chromen-2-one Usage And Synthesis
Chemical PropertiesWhite solid; walnut odor. Slightly soluble in alcohol.
UsesPerfumery, flavoring.
Uses7-Ethoxy-4-methylcoumarin was an analyte in a study of the structural characterization and retention time simulation of allergenic fragrances.
Uses7-Ethoxy-4-methylcoumarin may be used in the assay of 4-chlormethyl-7-ethoxycoumarin O-deethylase activity.
General Description7-Ethoxy-4-methylcoumarin (EtOMC), also known as ethyl 4-methylumbelliferyl ether, is a coumarin derivative. Its standard molar energy of combustion is ?5888.0 ± 3.2kJ·mol?1 and standard molar enthalpy of formation in the crystalline phase is ?545.4 ± 3.6kJ·mol?1.EtOMC can be prepared by reacting methyl acetoacetate with 3-ethoxyphenol in the presence of boron trifluoride dihydrate.The fluorescence quenching of EtOMC is more effective in the presence 4-hydroxy-TEMPO (4-hydroxy-2,2,6,6-tetramethylpiperidin-1-oxyl).
