Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its structure supports the formation of biologically active molecules by serving as a building block in heterocyclic chemistry. Commonly employed in medicinal chemistry for modifying pyrimidine-based compounds to enhance drug efficacy and selectivity. Also utilized in agrochemicals for the design of novel pesticides and herbicides due to its ability to interact with biological targets in pests and weeds. Its carboxylic acid functionality allows for easy derivatization, enabling the creation of amides, esters, and other functional groups important in structure-activity relationship studies.
