Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of antifungal and antibacterial agents. It serves as a building block in organic reactions due to the reactivity of its aldehyde and bromo functional groups. Commonly employed in cross-coupling reactions such as Suzuki and Heck reactions to form carbon-carbon bonds, enabling the construction of complex furan-containing molecules. Also utilized in the preparation of fluorescent dyes and functional materials where the furan ring acts as a π-conjugated spacer. Its derivatives show potential in medicinal chemistry for designing bioactive compounds with enhanced metabolic stability.
