A colourless liquid hydrocarbon, 3,7,11,15-tetramethylhexadecane, C20H42, that is the paraffin corresponding to phytol.
1907[see phytol]. 1911Chem. Abstr. V. 874 Phytane, C20H42, obtained by the reduction of phytol,..crystallizes in liquid air. 1965New Scientist 6 May 378/1 Certain hydrocarbons, such as the branched-chain compounds phytane and pristane, can if found [in rocks] be taken to be definite evidence of life. 1971Sci. Amer. May 38/3 The chemical analysis of organic material from the Gunflint cherts in several laboratories reveals the presence of the hydrocarbons pristane and phytane: two ‘chemical fossils’ that can most reasonably be regarded as being breakdown products of chlorophyll. |
