Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and receptor modulators. Its fluorinated aromatic structure enhances binding affinity and metabolic stability in drug candidates. Commonly employed in asymmetric synthesis to introduce chirality due to the presence of a stereogenic center. Also utilized in the preparation of fluorescent probes and labeled compounds for biochemical assays, leveraging the naphthyl group’s intrinsic fluorescence.
