Linalool Uses

 Linalool (CAS NO.78-70-6) is used as a scent in proportion of 60-80% of perfumed hygiene products and cleaning agents such as soaps, detergents, shampoos, lotions and so on. Besides, it is also used as a chemical intermediate. Additionally, linalool is usually used by pest professionals as a flea and cockroach insecticide.

Linalool Production

Biosynthesis of Linalool (CAS NO.78-70-6):
 Linalool is produced from isopentenyl pyrophosphate via the universal isoprenoid intermediate geranyl pyrophosphate, through a class of membrane-bound enzymes named monoterpene synthases.
