1128-08-1DTXSID4051584CHEMBL3728427CHEBI:143730化学的特性2-Pentyl-3-methyl-2-cyclopenten-1-one is a colorless, slightly viscous liquid with a typical jasmine odor, resembling that of the naturally occurring (Z)-jasmone. Dihydrojasmone is produced by an acid-catalyzed rearrangement of 4-methyl--decalactone, which is readily obtained by radical addition of 2-octanol to acrylic acid. Dihydrojasmone is used in perfumery in jasmine bases and, more generally, in floral and fruity fragrances.
