What is ISOJASMONE?

Chemical properties

2-Hexyl-2-cyclopenten-1-one is a pale straw-colored liquid. Boiling range 219 to 238℃. Sp.Gr. 0.91. The odor is mere fruity, less floral than that of Dihydro jasmone.

The Uses of ISOJASMONE

2-Hexyl-2-cyclopenten-1-one is used in perfume compositions for its floral effect mainly in such florals where a distinctly fruity note is acceptable or even desirable ( "White Shoulders" - type of fragrance). It blends well with the heavy fruity notes from Undecanolide and the musky notes from Ethylene brassylate or newer synthetic musks. Ionones and particularly Methylionones supply very good background for this Jasmone-derivative. The use in flavors is very small, since the I taste of this mixture is inferior to that of Dihydro jasmone and other single chemicals.
