Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nonsteroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules. Its structure allows for further functionalization, making it valuable in constructing complex organic compounds. Commonly employed in heterocyclic synthesis, especially for forming fused ring systems used in medicinal chemistry. Also utilized in the preparation of dyes and agrochemicals due to its reactive amino and ester groups.
