citronellic

Citronellic is a term that can refer to a few different chemical compounds, primarily related to citronellol. Most commonly, it refers to citronellal, an organic compound found in the oils of several plants, particularly citronella grass and rose bushes. Citronellal is a key component responsible for the characteristic lemony scent of these plants. It is an aldehyde and is widely used in the fragrance and flavor industries.

Another related compound is citronellic acid, also known as 3,7-dimethyl-6-octenoic acid. This carboxylic acid is derived from citronellol and has a less intense odor than citronellal. It is also found naturally in some plants and can be synthesized. Citronellic acid has applications in the synthesis of other chemicals and in some cosmetic formulations.

The term might also occasionally be used loosely to describe derivatives or related compounds of citronellol, a monoterpene alcohol that is a major constituent of citronella oil. This alcohol is also extensively used in perfumery and as an insect repellent. The specific meaning of "citronellic" often depends on the context in which it is used.
