Useful:

• Chemical Classes: Other Classes -> Aliphatics, Saturated (>C11)
• Canonical SMILES: CCC(C)CCCC(C)CCCC(C)CCCC(C)C
• Uses: Phytane is a useful intermediate, which is involved in the manufacturing and analysis of various compounds. Phytane has recently been used in the development of a stable and environmental-friendly lubricating oil. By determining the ration of !3C to 12C in phytane isolated from ocean sediments researchers in the Netherlands have been able to quantify CO2 levels reaching back to the Cambrian period when animals emerged on the earth.
