Phloretic acid is a phenolic compound.

The enzyme phloretin hydrolase uses phloretin and H₂O to produce phloretate and phloroglucinol.

It is found in the rumen of sheep fed with dried grass and is produced by hydrogenation of the 2-propenoic side chain of p-coumaric acid. It is also an urinary metabolite of tyrosine in rats.

It can be used to produce polyesters based on phloretic acid and gallic acid.
