| | 2-PENTYL-2-CYCLOPENTEN-1-ONE Usage And Synthesis |
| Odor | Fruity, fresh-floral and Jasmin-like odor, but it lacks the“bread-like”note of the Jasmine, a note found in cis-Jasmone and in the Methyl jasmonates. The odor of Amyl cyclopentenone is not as rich as the odor of the named materials.
| | Chemical Properties |
Amyl cyclopentenone is a colorless or very pale straw-colored liquid.Insoluble in water.
| | Uses |
Amyl cyclopentenone is suggested for use in perfume compositions, primarily in the creation of artificial Jasmin, Jasmin bases, specialties, etc. It can also be used as a floralizer for fragrances other than those of the Jasmin type, mainly in the milder florals, and in a few sharper ones, such as Hyacinth.
| | Preparation |
Amyl cyclopentenone is prepared from Decenoic acid by treatment with Phosphoric acid.
