The molecule consists of a 2-propenyl group (CH2=C-CH3) affixed to the 4 position of phenol.
The compound is an intermediate in the production of bisphenol A (BPA), 2.7 Mkg/y of which are produced annually (2007).
It is also generated by the recycling of o,p-BPA, a byproduct of the production of the p,p-isomer of BPA.
[1] The high-temperature hydrolysis of BPA gives the title compound together with phenol:[2] The compound can also be produced by catalytic dehydrogenation of 4-isopropylphenol.
[3] 4-Isopropenylphenol undergoes O-protonation by sulfuric acid, giving the carbocation, which undergoes a variety of dimerization reactions.
