Used as a key intermediate in organic synthesis, particularly in the preparation of functionalized polymers and specialty chemicals. Its reactive bromine and terminal alkene groups allow for selective reactions, such as palladium-catalyzed couplings and radical additions, making it valuable in pharmaceutical and agrochemical research. It also serves as a building block in the synthesis of surfactants, lubricants, and crosslinking agents due to its bifunctional reactivity and hydrophobic chain length.
