Used in organic synthesis as a building block for pharmaceuticals and fine chemicals. Acts as a Michael acceptor in conjugate addition reactions due to the electron-deficient double bond conjugated with the ester group. Employed in the preparation of naphthalene-based derivatives for research in materials science, including potential applications in organic semiconductors and fluorescent dyes. Also explored in medicinal chemistry for designing compounds with biological activity, leveraging the naphthalene moiety's affinity for aromatic interactions in biomolecular binding.
