Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of anti-inflammatory and central nervous system agents. Its aromatic and carboxylic functional groups allow for derivatization into esters, amides, or other bioactive molecules. Commonly employed in medicinal chemistry for structure-activity relationship studies due to the chlorophenyl moiety’s influence on lipophilicity and receptor binding. Also utilized in the preparation of specialty chemicals and agrochemicals where substituted phenylpropanoic frameworks are required.
