Used as a key intermediate in the synthesis of nonsteroidal anti-inflammatory drugs (NSAIDs), particularly naproxen derivatives. Its brominated naphthalene structure allows for selective cross-coupling reactions in organic synthesis, enabling the construction of complex biaryl systems. Commonly employed in pharmaceutical research to develop analgesic and antipyretic agents. Also utilized in the preparation of fluorescent probes due to the naphthalene moiety’s inherent photophysical properties, making it valuable in biochemical labeling and imaging studies.
