2-Phenyl 2-butenal (FEMA #3224, CAS #4411-89-6) has a very attractive cocoa aroma, softer than 5-methyl 2-phenyl 2-hexenal, perhaps less distinctive but definitely less strident. This note is paired with an equally soft and pleasant tinge of honey. These two notes obviously work well together in brown flavors. Their combination also add interest, at modest levels, in quite a smorgasbord of other flavors.
