Geranyl linalool is a colorless and transparent liquid. Structurally, geranyl linalool is a straight chain diterpenoid. Being bioactive natural product, geranyl linalool is the essential ingredients that determine the spice type. In the other hand, geranyl linalool was also an important intermediate for Teprenone, a gastric mucosa protective agent. Employing geranyl linalool as substrate, the most convenient synthesis method of Teprenone would be achieved. Catalyzed by isopropanol aluminum and reacted with methyl acetoacetate, Teprenone could be obtained in one step. Geranyl linalool can also be used as insect pheromone and natural insect insecticide. So, geranyl linalool possesses important economic value.
