Used as a reactive intermediate in organic synthesis, particularly in the preparation of naphthalene-based derivatives for pharmaceuticals and fine chemicals. Its strained epoxide ring undergoes ring-opening reactions with nucleophiles, enabling the introduction of functional groups at specific positions on the aromatic system. Commonly employed in the development of dyes, fluorescent probes, and polymer modifiers due to its ability to participate in cycloaddition and coupling reactions. Also serves as a building block in the synthesis of polycyclic compounds for materials science applications.
