Used as a key intermediate in organic synthesis, particularly in pharmaceuticals and agrochemicals. Its alkyne functionality allows for coupling reactions, such as Sonogashira and click chemistry, enabling the construction of complex molecules. Commonly employed to introduce bromoalkyl spacers in drug design, facilitating conjugation with biomolecules or functional materials. Also utilized in polymer chemistry to modify resin properties or create cross-linkable systems. Its reactivity makes it valuable in research for developing new bioactive compounds and functionalized materials.
