General description

7-Methyl-2H-1,5-benzodioxepin-3(4H)-one, a synthetic fragrance ingredient, belongs to the group of marine odorants. It is sought for its olfactory impression of a seashore with floral notes. This benzodioxepinone possesses a molecular framework desirable for the study of structure-odor relationships (SOR).[1][2]

Application

7-Methyl-2H-1,5-benzodioxepin-3(4H)-one may be used as an analytical standard for the determination of the analyte in the olfactory evaluation of synthetic marine odorant formulations by various chromatographic techniques.[1][3][2]
