7-Ethoxy-4-methyl-2H-chromen-2-one Chemical Properties,Usage,Production

Chemical Properties

White solid; walnut odor. Slightly soluble in alcohol.

Uses

Perfumery, flavoring.

Uses

7-Ethoxy-4-methylcoumarin was an analyte in a study of the structural characterization and retention time simulation of allergenic fragrances.

Uses

7-Ethoxy-4-methylcoumarin may be used in the assay of 4-chlormethyl-7-ethoxycoumarin O-deethylase activity.

Definition

ChEBI: 7-Ethoxy-4-methyl-2H-1-benzopyran-2-one is a member of coumarins.

General Description

7-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).

Synthesis

Prod.:
1) from Diketene plus Resorcinol with sulfuric acid to produce 4-Methyl-7-hydroxy - coumarin. Ethylation produces subject material.
2) from Resorcinol plus Ethylacetoacetate, followed by Ethylation.
