Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of nonsteroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules. Its structure allows for selective modification in multi-step organic reactions, making it valuable in constructing complex drug scaffolds. Commonly employed in peptide coupling and protection strategies due to the presence of both carboxylic acid and protected amine functionalities. Widely utilized in research settings for creating analogs in medicinal chemistry programs.
