| (-)-CITRONELLAL Usage And Synthesis |
| Chemical Properties | CLEAR COLOURLESS TO PALE YELLOW LIQUID | | Uses | (S)-(-)-Citronellal may be used in the synthesis of bioactive compounds like (+)-hexahydrocannabinol, (S)-isopulegol, machaeriols A and B. | | Definition | ChEBI: The (3S)-stereoisomer of 3,7-dimethyloct-6-enal (citronellal). | | General Description | (S)-(-)-Citronellal is a monoterpenoid compound mainly found in Corymbia citriodora and Cymbopogon nardus essential oils. | | Purification Methods | Fractionally distil it. Alternatively extract it with NaHSO3 solution, wash it with Et2O, then acidify it to decompose the bisulfite adduct and extract with Et2O, dry (Na2SO4), evaporate and distil. Check for purity by hydroxylamine titration. The ORD in MeOH (c 0.167) is: []700 +9o, []589 +11o, []275 +12o and []260 +12o. The semicarbazone has m 85o, and the 2,4-dinitrophenylhydrazone has m 79-80o. [(+)-compound: Tietze & Beifuss Org Synth 71 167 1993, IR: Carroll et al.
