Descriptors

An intensely pungent, solvent-like ketone with a sharp, penetrating character reminiscent of acetone or peppermint camphor. On drying it reveals a faint honey-like sweetness, but the dominant impression is harsh and irritating — rarely used in perfumery today except in trace amounts.AI · claude-opus-4-7

Appearance

Colorless oily liquid.

Solubility

0% soluble in water, miscible with alcohol and oils, soluble in Propylene glycol.

Odor

The commercial grade has an unpleasant odor, sometimes gassy, green or vegetable-pungent, acrylic. However, the pure material has a fairly pleasant odor, almost honey-like in dilution - reminiscent of iso-Phorol and iso-Phorone, and one can observe a breadlike sweetness in this volatile fragrance.

Uses in perfumery

This ketone finds a little use as a masking agent in industrial perfumes.

Production

Produced from Acetone or Diacetone alcohol by reacting with Iodine or with other dehydrating agents.
