IUPAC name of ferulic acid is called 3-(4-hydroxy-3- methoxyphenyl) propenoic acid. Ferulic acid is commercially available in the form of a white to off-white crystalline powder. It forms two geometric (cis and trans) isomers. The trans isomer is a white crystalline substance whereas the cis-isomer is a yellowish liquid substance. Ferulic acid occurs mainly as a trans isomer.

Phenolic compounds are comprised of a heterogeneous class of natural products with an aromatic ring moiety linked to one or more hydroxyl groups. Phenolics are usually divided into simple phenols, phenolic acids, and polyphenols.
