Product Name:3,7-Dimethyl-7-hydroxyoctanal
CAS Number:107-75-5
Molecular formula:C10H20O2
Molecular Weight:172.26

By hydration of natural citronellal obtained from Java citronella or from Eucalyptus citriodora; β-pinene is converted to myrcene, which on hydration may yield either linalool or 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.

trans-Citral = trans-3,7-Dimethyl-octa-2,6-dien-1-al
