4-ALLYLPHENOL is very slightly soluble in water, soluble in
alcohol. miscible with oils. | [Occurrence]
Reported found in Alpinia galanga oil (0.20%), bay leaf oil (<0.01–15.51%), bay leaf oil anise (0.8%), bay leaf
oil clove (17.1%), and betel leaf. | [Uses]
4-Allylphenol is a useful building block naturally occurring in Syzygium aromaticum leaves. 4-Allylphenol has been used in the synthetic, regioselective preparation of gamma-lactones. | [Application]
4-ALLYLPHENOL is suggested for use in perfume compositions
for "leather" or "smoke" effects, dry notes,
etc. and - in the functional product - as an
antiseptic.
Unstable under alkaline conditions, discolors in the presence of Iron and other metals
in trace amounts. | [Definition]
ChEBI: A phenylpropanoid that is phenol substituted by a prop-2-enyl group at position 4. | [Production Methods]
4-ALLYLPHENOL can be produced from Estragole (Methyl chavicol) by
Grignard reaction with Ethyl Magnesium
Bromide. Can also be isolated from Betel oil. | [Aroma threshold values]
High strength odor; phenolic type; recommend smelling in a 0.10% solution or less |
