Product Details

3,7-Dimethyl-7-hydroxyoctanal CAS#107-75-5

Hydroxycitronellal has an intense, sweet, floral, lily-type odor. It may be prepared by hydration of natural citronellal obtained from Java citronella or from Eucalyptus citriodora; P-pinene is converted to myrcene, which on hydration may yield either linalool or a mixture of geranoil and nerol; the latter mixture can be hydrogenated to citronellol and subsequently converted to citronellal and hydroxycitronellal; also by hydrogenation of 3,7-dimethyl- 7-hydroxy-2-octen-2-al over palladium carbon in ethyl acetate solution.
