Use

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.
