In chemistry

-ine is a suffix used in chemistry to denote two kinds of substance. The first is a chemically basic and alkaloidal substance. Examples include quinine, morphine and guanidine. The second usage is to denote a hydrocarbon of the second degree of unsaturation. Examples include hexine and heptine. With simple hydrocarbons, this usage is identical to the IUPAC suffix -yne.

Many commercial and popular names also use this suffix; gasoline and vaseline for example.
