3,3,5-Trimethylcyclohexanol Usage And Synthesis

Chemical Properties

3,3,5-Trimethyl cyclohexanol has a menthol-like camphorous odor.

Chemical Properties

WHITE CRYSTALLINE MASS. Soluble in most organic solvents, hydrocarbons, oils; insoluble in water. Combustible.

Occurrence

Has apparently not been reported to occur in nature.

Uses

Menthol and camphor substitute, antifoaming agent, hydraulic fluids and textile soaps, odor masking, esterification agent, pharmaceuticals,wax additive, printing inks.

Definition

ChEBI: A secondary alcohol that is cyclohexanol substituted by two methyl groups at the 3-position and one methyl group at the 5-position. It exhibits inhibitory activity against HMG-CoA reductase ( EC 1.1.1.34/EC 1.1.1.88).

Preparation

By complete hydrogenation of isophorone (Arctander, 1969).

Synthesis Reference(s)

Tetrahedron, 37, p. 1171, 1981 DOI: 10.1016/S0040-4020(01)92046-0

Hazard

Toxic by inhalation, strong irritant.
