Used in the synthesis of pharmaceutical intermediates, particularly in the development of anti-inflammatory and anticancer agents. Its naphthalene core with functionalized substituents makes it valuable in organic synthesis for constructing complex polycyclic molecules. Commonly employed in research settings to design bioactive compounds due to its ability to interact with enzyme active sites and cellular receptors. Also utilized in the preparation of fluorescent probes and dyes, benefiting from its aromatic structure that supports light absorption and emission properties.
