Used primarily as a monomer in the synthesis of specialty polymers and resins, 2-vinylnaphthalene contributes to materials with enhanced thermal stability and mechanical strength. Its aromatic structure improves the rigidity and heat resistance of resulting polymers, making them suitable for high-performance coatings, adhesives, and electronic encapsulants. It is also employed in the production of fluorescent compounds and optical brighteners due to its light-emitting properties when polymerized or chemically modified. Additionally, it serves as an intermediate in organic synthesis for pharmaceuticals and fine chemicals where a naphthalene backbone is required.
