Used in organic synthesis as an intermediate for pharmaceuticals and fine chemicals. Its aldehyde group allows for condensation reactions, making it valuable in constructing complex aromatic systems. Commonly employed in the development of dyes and fluorescent compounds due to the naphthalene core's photophysical properties. Also utilized in the preparation of ligands for metal-organic frameworks and catalysts. Its methoxy substituents enhance electron density, improving reactivity in electrophilic substitution and aiding in the stabilization of reaction intermediates.
