What is CONIFERYL ALCOHOL?

Chemical properties

beige crystalline powder

Physical properties

White (colorless) crystals. M.P. 74°C. Very slightly soluble in water, soluble in alcohol and oils.

The Uses of CONIFERYL ALCOHOL

Coniferyl alcohol was used as a fungal growth inhibitor.

Definition

ChEBI: A phenylpropanoid that is one of the main monolignols, produced by the reduction of the carboxy functional group in cinnamic acid and the addition of a hydroxy and a methoxy substituent to the aromatic ring.

What are the applications of Application

CONIFERYL ALCOHOL can polymerize with weak mineral acids and certain organic acids, turning into an amorphous, odorless gum. This chemical could find extensive use as a fixative and blender in various types of floral, balsamic and Oriental fragrances. However, it is not generally available in the state of chemical or olfactory purity desirable to the perfumer.

General Description

Coniferyl alcohol is one of the preferred substrate of the eucalpytus globus enzyme.

Purification Methods

It is soluble in EtOH and insoluble in H2O. It can, however, be recrystallised from EtOH and distilled in a vacuum. It polymerises in dilute acid. The benzoyl derivative has m 95-96o (from pet ether), and the tosylate has m 66o.
