The suffix -ane is used in organic chemistry to form names of organic compounds where the -C-C- group has been attributed the highest priority according to the rules of organic nomenclature. The final "-e" disappears if it is followed by a suffix that starts with a vowel, e.g. "propanol".[1]

Alternatively, it may refer to a mononuclear hydride of an element, for instance, methane for CH4 and oxidane for water. [2] For the etymology of the term, see Alkane.
