General description

α-Terpineol is a cyclic monoterpene. It is one of the major monoterpenol component of the cultivar Gewürztraminer and other aroma-rich grape varieties. α-Terpineol, a monoterpenoid alcohol, has been investigated for its anticonvulsant activity. It was one of the insecticidal constituent of the essential oils of Dahlia pinnata.FCC includes the following isomers in the listed purity: alpha-, (E)-beta, (Z)-beta, gamma-, terpinen-4-ol, and terpinen-1-ol.

Application

α-Terpineol is the suitable aroma standard used to study the influence of the drying method on volatile compounds of Origanum vulgare. It may be employed as a highly viscous solvent in the preparation of photocatalytic transparent TiO2 thin film.
