Eugenol

 

(also 4-allyl-2-methoxyphenol), a yellowish liquid having the structural formula

Eugenol has the odor of cloves. It is soluble in alcohol and ether and slightly soluble in water. It has a melting point of 10.3°C, a boiling point of 252.7°C, and a density of 1.066 g/cm3 at 20°C. Eugenol is extracted from essential oils, including clove oil, which has a eugenol content of up to 95 percent, and the oil of East Indian basil, which is approximately 70 percent eugenol. It can be synthesized from such compounds as guaiacol.

Eugenol is used as an aromatic substance in the manufacture of perfumes and vanillin.
