Paracoumaryl alcohol is a phytochemical, one of the monolignols.

p-Coumaryl alcohol is a major precursor to lignin or lignans.

[1] It is synthesized via the phenylpropanoid biochemical pathway.

Esters of p-coumaryl alcohol and fatty acids are the basis of epicuticular waxes covering the surfaces of apples.

p-Coumaryl alcohol is an intermediate in biosynthesis of chavicol, stilbenoids, and coumarin.
