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 designing kinase inhibitors and other targeted therapies. Also utilized in research settings to develop fluorescent probes due to its ability to form stable derivatives with detectable emission properties. Its carboxylic acid and amino groups allow for easy functionalization, making it valuable in combinatorial chemistry and drug discovery.
