α-santalol

α-Santalol, C15H24O, is the sesquiterpene alcohol the house’s sandalwood essay names as the oil’s principal molecule. Its identity is PubChem’s.

A study of the oil’s biosynthesis names it, with β-santalol, as the most important contributor to the scent of sandalwood oil. No share is given: the study’s figure is for four molecules together.
