Used as an intermediate in the synthesis of pharmaceuticals and fine chemicals, particularly in the production of non-steroidal anti-inflammatory drugs (NSAIDs). Its structure allows for further functionalization, making it valuable in building complex organic molecules. Also employed in research settings for developing fluorescent probes and dyes due to the naphthalene moiety’s inherent photophysical properties. The chloroethoxy group facilitates coupling reactions, enabling its use in polymer chemistry and material science applications.
