Caffeic acid is an organic compound that is classified as a hydroxycinnamic acid. This yellow solid consists of both phenolic and acrylic functional groups. It is found in all plants because it is a key intermediate in the biosynthesis of lignin, one of the principal components of woody plant biomass and its residues.. Reference standards of Caffeic Acid API, and its pharmacopeial, non pharmacopeial impurities, and stable isotopes are listed below
