Used primarily as an intermediate in organic synthesis, this compound serves in the construction of complex cyclic and strained ring systems. Its reactive bromoalkylidene functionality allows for carbon-chain extension and cyclization reactions, making it valuable in pharmaceutical and agrochemical research. It is often employed to introduce cyclopropyl-containing moieties into target molecules, which can enhance metabolic stability and binding affinity in bioactive compounds. Additionally, it finds use in materials science for designing specialty monomers and functionalized polymers with tailored reactivity.
