Metabolite Identification
Common Name4-Methoxycinnamic acid
Description4-Methoxycinnamic acid, also known as para-methoxycinnamate or O-methyl-p-coumarate, belongs to the class of organic compounds known as cinnamic acids. These are organic aromatic compounds containing a benzene and a carboxylic acid group forming 3-phenylprop-2-enoic acid. 4-Methoxycinnamic acid exists as a solid, possibly soluble (in water), and an extremely weak basic (essentially neutral) compound (based on its pKa) molecule.
