Citronellic acid has a green-grassy odor. | [Chemical Properties]
CLEAR COLOURLESS TO LIGHT YELLOW LIQUID | [Occurrence]
The d-form is reportedly a constituent of Java citronella, geranium, Borosma pulchellum, Xanthoxylum
piperitum, bitter-orange leaves, lemongrass, Calytrix virgata and Calytrix tetragona leaves; the l-form has been reportedly identified
in cypress oil (Callitirs glauca R. Br.), Callitirs intratropica, in the oil of Chamaecyparis obtusa and of Thujopsis dolabrata;
the d,l-form is isolated from camphor oil. Also reported found in mandarin peel oil, swangi (Citrus hystrix D.C.), peppermint oil
and black tea. | [Uses]
Citronellic acid was used in synthesis of stereoisomers of 3,11- dimethylnonacosan-2-one and 29-hydroxy-3,11-dimethylnonacosan-2-one. | [Definition]
ChEBI: Citronellic acid is a monounsaturated fatty acid that is oct-6-enoic acid carrying methyl groups at positions 3 and 7. It has a role as a plant metabolite and a flavouring agent. It is a monoterpenoid, a medium-chain fatty acid and a monounsaturated fatty acid. It is functionally related to a citronellal. | [Preparation]
By oxidation of citronellal; also by the conversion of pulegone. | [Aroma threshold values]
Detection at 1%: fatty, waxy, heavy, floral with a slight citronella nuance. It also has vegetative and tobacco
nuances. | [Taste threshold values]
Taste characteristics at 5 to 30 ppm: mild, floral, rosy, fruity melon with slight hints of citronella and citrus. |
