What is p-Menthane-3,8-diol?

Chemical properties

p-Menthane-3,8-diol has a faint minty, herbaceous, eucalyptus-like odor. The cooling power is reported to be approxi mately 9.5 times that of (-)-menthol.

Occurrence

Reportedly present in the lemon eucalyptus plant(Eucalyptus citriodora tree), which is native to Australia, but is now cultivated in many warm places around the world.

The Uses of p-Menthane-3,8-diol

2-Hydroxy-α,α,4-trimethylcyclohexanemethanol is used in protection measures in the prevention of tick-born diseases. Acaricide.

Preparation

In a patented method, citronellal is treated with aqueous sulfuric acid to produce p-menthane-3,8-diol. Also produced by an extraction process utilizing lemon eucalyptus oil.

Definition

ChEBI: P-menthane-3,8-diol is a p-menthane monoterpenoid in which p-menthane carries hydroxy groups at C-3 and C-8. It derives from a hydride of a p-menthane.
