Chemical Properties

Citronellal has an intense, lemon-, citronella-, rose-type odor.

Uses

rac-Citronellal is a monoterpenoid and the major isolate in citronella oil. Citronella oil is an essential oil bearing insecticidal properties. rac-Citronellal is also often used as a fragrance ingred ient.

Definition

ChEBI: A monoterpenoid, the main component of citronella oil which gives it its distinctive lemon aroma.

Aroma threshold values

Detection: 31 to 100 ppb

Taste threshold values

Taste characteristics at 10 ppm: floral, green, rosy and citrus-lemon.

Chemical Synthesis

Can be prepared by chemical synthesis or by fractional distillation of natural oils, such as citronella. Industrially prepared by hydrogenation of β-citronellol or by catalytic hydrogenation of citral; also in the laboratory by dehydration of hydroxydihydrocitronellal.
