Citral, or 3,7-dimethyl-2,6-octadienal or lemonal, is either of a pair of terpenoids with the molecular formula C10H16O. The two compounds are double bond isomers. The E-isomer is known as geranial or citral A. The Z-isomer is known as neral or citral B.
Geranial has a strong lemon odor. Neral has a lemon odor that is less intense, but sweeter. Citral is therefore an aroma compound used in perfumery for its citrus effect. Citral is also used as a flavor and for fortifying lemon oil. It also has strong anti-microbial qualities, and pheromonal effects in insects.
Health & Safety information
Citral should be avoided by people with perfume allergy.
