Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of fluorinated organic compounds where the fluorine atom enhances metabolic stability and bioavailability. Its structure supports the creation of complex molecules in medicinal chemistry, especially in routes requiring aromatic fluorination. Also employed in the preparation of fluorescent dyes and optical materials due to the naphthalene backbone’s inherent photophysical properties. Serves as a building block in organic synthesis for cross-coupling reactions, enabling the construction of biaryl systems and functionalized aromatic networks.
