Used as an intermediate in the synthesis of pharmaceuticals and fine chemicals, particularly in the preparation of heterocyclic compounds. It serves as a building block for indole derivatives, which are important structures in medicinal chemistry. Commonly employed in the development of non-steroidal anti-inflammatory drugs (NSAIDs) and other biologically active molecules. Its amine and ester functionalities allow for versatile chemical modifications, making it valuable in organic synthesis and drug discovery research.
