(7E,9E)-Beta-Ionylidene Acetaldehyde

(7E,9E)-Beta-Ionylidene Acetaldehyde is a conjugated diene aldehyde derived from the cyclohexene core of Ionylidene, featuring a (7E,9E)-configured trans-double bond system and an Ξ±,Ξ²-unsaturated aldehyde moiety at the Ξ²-position relative to the ionone skeleton. Its structure incorporates a branched isoprenoid side chain with a terminal acetaldehyde group, conferring electrophilic reactivity. This compound arises as a stereospecific oxidation byproduct during Ionylidene synthesis, retaining the parent’s tricyclic framework but with altered conjugation. It serves as an HPLC reference standard for quantifying aldehyde-derived impurities in Ionylidene formulations.
