Application

1-Fluoronaphthalene serves as a versatile fluorinated precursor in organic synthesis, particularly for Suzuki-Miyaura cross-coupling reactions to create biaryl compounds. It is also used as a solvent in NMR spectroscopy due to its distinct ¹⁹F signal. In materials science, it acts as a monomer for fluorinated polymers with enhanced thermal and chemical resistance.
