Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of nonsteroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules. Its structure allows for functionalization at multiple sites, making it valuable in constructing complex organic compounds. Commonly employed in medicinal chemistry for building aromatic frameworks with amine and ester functionalities. Also utilized in the preparation of dyes and specialty polymers where aromatic amino acids with polar substituents are required.
