What is 4-Hydroxycinnamic acid?
The Uses of 4-Hydroxycinnamic acid
An antioxidative active compound isolated from the EtOAc layer of MeOH extracts of kochujang, Korean fermented red pepper paste. Photoisomerization of ionic liquid ammonium cinnamates. Cinnamic acids upon irradiation in solution undergo geometric isomerization while dimerizing to different dimers in the crystalline state.
