Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. Its protected amine group allows for selective reactions in multi-step organic syntheses, making it valuable in drug discovery. Commonly employed in the preparation of pyrazole-based scaffolds found in anti-inflammatory, anticancer, and antiviral agents. The carboxylic acid functionality enables coupling reactions with amines or alcohols to form amides or esters, facilitating structural diversification in medicinal chemistry.
