Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antifungal and antibacterial agents. It serves as a building block in organic synthesis due to the reactivity of its aldehyde and heterocyclic groups. Employed in the development of agrochemicals, including certain pesticides and herbicides, where its chlorinated furan structure contributes to bioactivity. Also utilized in the preparation of dyes and functional materials, where it acts as a precursor for more complex aromatic systems. Its versatility in cross-coupling reactions makes it valuable in research and development of new chemical entities.
