(-)-CITRONELLAL Usage And Synthesis

Chemical Properties

CLEAR COLOURLESS TO PALE YELLOW LIQUID

Definition

ChEBI: The (3S)-stereoisomer of 3,7-dimethyloct-6-enal (citronellal).

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.
