Used in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs), particularly as an intermediate in producing naproxen derivatives. It serves as a chiral building block in pharmaceutical chemistry, enabling the development of enantiomerically pure compounds with improved therapeutic profiles. Its structure supports conjugation and functional group modifications important in drug design. Also explored in the preparation of fluorescent probes due to the naphthalene moiety, useful in biochemical imaging and sensor applications.
