Pristane

Pristane is a natural saturated terpenoid alkane obtained primarily from shark liver oil. It is a transparent oily liquid that is immiscible with water, but soluble in diethyl ether, benzene, chloroform and carbon tetrachloride.

It is used as a lubricant, a transformer oil, and an anti-corrosion agent.

Biosynthetically, pristane is derived from phytol.

Pristane was named after Latin pristis, "shark".
