Used in organic synthesis as an intermediate for pharmaceuticals and fine chemicals. Its structure supports the development of bioactive molecules, particularly in the preparation of heterocyclic compounds with potential medicinal properties. Commonly employed in research settings to construct complex furan-based frameworks found in certain drug candidates. Also utilized in the synthesis of fluorescent dyes and optical materials due to the inherent electronic properties of the benzo[b]furan core. Shows utility in the development of sensors and functional materials where aromatic heterocycles enhance performance.
