(E,E)-Farnesol Usage And Synthesis
  • Chemical PropertiesClear Colourless Oil
  • UsesFarnesol is a natural organic compound which is present in many essential oils.
  • Synthesis Reference(s)Journal of the American Chemical Society, 102, p. 3298, 1980 DOI: 10.1021/ja00529a091
    The Journal of Organic Chemistry, 40, p. 3617, 1975 DOI: 10.1021/jo00912a039
  • Purification MethodsThe main impurity is the cis-trans isomer. Purify it by gas chromatography using a 4ft x 0.125in 3%OV-1 column at 150o. [Corey et al. J Am Chem Soc 92 6637 1970, Popjak et al. J Biol Chem 237 56 1962.] It has also been fractionated through a 14-in Podbielniak column (p 11) at 11o/0.35mm. Alternatively it has been purified by gas chromatography using SF96 silicone on Fluoropak columns or Carbowax 20M on Fluoropak or base-washed 30:60 firebrick (to avoid decomposition, prepared by treating the firebrick with 5N NaOH in MeOH and washed with MeOH to pH 8) at 210o with Helium carrier gas at 60 mL/min flow rate. The diphenylcarbamoyl derivative has m 61-63o (from MeOH) and has an IR band at 3500 cm-1. [Bates et al. J Org Chem 28 1086 1963, Beilstein 1 IV 2335.]
