Description3-(2-Hydroxyphenyl)propanoic acid, also known as melilotic acid or melilotate, belongs to the class of organic compounds known as phenylpropanoic acids. Phenylpropanoic acids are compounds with a structure containing a benzene ring conjugated to a propanoic acid. 3-(2-Hydroxyphenyl)propanoic acid exists in all living organisms, ranging from bacteria to humans. 3-(2-Hydroxyphenyl)propanoic acid is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. 3-(2-Hydroxyphenyl)propionic acid is found in Cinnamomum cassia , Dipteryx odorata, Justicia pectoralis and Melilotus albus. 3-(2-Hydroxyphenyl)propionic acid was first documented in 1964 (PMID: 14243380). Based on a literature review a small amount of articles have been published on 3-(2-Hydroxyphenyl)propanoic acid (PMID: 14269315) (PMID: 4192639) (PMID: 7483862).
