Metabolite Identification
Common Name7,7-Diethoxy-3-heptene
Description7,7-Diethoxy-3-heptene, also known as cis-4-heptenal diethyl acetal, is a member of the class of compounds known as acetals. Acetals are compounds having the structure R2C(OR')2 (R' is not hydrogen) and are thus diethers of geminal diols. Originally, the term was confined to derivatives of aldehydes (one R = H), but it now applies equally to derivatives of ketones (neither R = H). Mixed acetals have different R' groups. 7,7-Diethoxy-3-heptene is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). 7,7-Diethoxy-3-heptene is a flavouring ingredient used to impart cream or butter-like flavour (FEMA 3349), and it is used as a food additive (EAFUS: Everything Added to Food in the United States).
