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 optimizing drug candidates due to its favorable binding properties with biological targets. Also utilized in the preparation of kinase inhibitors and antimicrobial compounds. Its carboxylic acid functionality allows for easy derivatization, enabling the creation of amides, esters, and other functional groups important in drug design.
