A sharp, intensely lemony aldehyde with a green, slightly grassy edge and a waxy-fatty undertone. Opens bright and citrus-peel-like with a metallic sparkle, then softens into a slightly soapy, herbaceous facet reminiscent of citronella and lemongrass.AI · claude-opus-4-7

Perfume and Flavor Chemicals, page 276.
Colorless mobile liquid.
Very slightly soluble in water, soluble in alcohol and oils.
Powerful, fresh, green-citrusy, slightly woody odor, lacking in sweetness and fruitiness as compared to Citral, and more suggestive of Citronella oil, inevitably if the observer is familiar with that oil.
Citronellal is occasionally used — in traces - in flavor compositions of the Citrus, Cherry, Fruit (tutti-frutti), Ginger Ale, Spice and other types.
This aldehyde is rather unstable under exposure to air, daylight and alkali, and is therefore not much used as such in perfumes or flavors. Citronella oil is less expensive and more stable. It gives a more attractive picture of the Citronellal odor in its natural modification and composition.
1) By isolation from Eucalyptus Citriodora oil or from Java/Formosa/Guatemala type of Citronella oil. 2) Synthetically from Pinene. 3) By dehydrogenation of Geraniol.
