Used as a reactive monomer in polymer synthesis, particularly in the development of functional resins and coatings. Its hydroxyl and methacrylate groups enable dual reactivity, allowing for crosslinking and improved adhesion to various substrates. Commonly applied in photoresists and UV-curable systems due to its ability to participate in free radical polymerization. Also serves as an intermediate in the production of dyes and optical brighteners, leveraging the naphthalene core for enhanced light absorption and fluorescence properties. Its structure supports use in specialty polymers requiring thermal stability and rigidity.
