Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of agrochemicals and bioactive molecules. Its structure allows for functionalization that supports the creation of compounds with herbicidal and insecticidal properties. It is also employed in medicinal chemistry for constructing nitrogen-containing heterocycles, which are common in drug discovery programs targeting inflammation and central nervous system disorders. The carboxylic acid group enables easy derivatization into esters, amides, or other functional groups to fine-tune solubility and binding characteristics in lead compounds.
