Citronellal

 

(also 3,7-dimethyl-6-octenal), the terpene aldehyde (CH3)2C═CH(CH2)2CH(CH3)CH2CHO. Citronellal is a colorless liquid with a pleasant, lemonlike odor. Insoluble in water, it is soluble in alcohol and ether. It has a boiling point of 206.9°C and a density of 0.855 g/cm3 at 20°C.

Citronellal is a component of many essential oils. It is obtained from these oils—particularly citronella oil—by rectification or by a process yielding a bisulfite derivative. Citronellal is used as an ingredient of perfumes and as a raw material in the production of fragrant substances, such as citronellol and hydrocitronellal.
