Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its reactive acid chloride group allows it to form amide or ester derivatives, making it valuable in constructing bioactive molecules. Commonly employed in the development of fragrances and flavoring agents due to the aromatic character of the benzofuran core. Also utilized in the synthesis of functional materials, including liquid crystals and organic semiconductors, where substituted benzofurans contribute to electronic properties.
