Used as an intermediate in the synthesis of nonsteroidal anti-inflammatory drugs (NSAIDs), particularly in the production of naproxen analogs, which are widely used pain relievers and fever reducers. Its structure allows for efficient derivatization to form active pharmaceutical ingredients. Also employed in the development of dyes and fluorescent probes due to its aromatic and amine functionalities, which enhance light absorption and emission properties. Its ethoxy and amine groups make it suitable for coupling reactions in organic synthesis.
