Used primarily as a coupling agent in the synthesis of organosilicon compounds, enabling the attachment of organic molecules to silica surfaces or polymers. Commonly applied in surface modification of glass, silicon wafers, and nanoparticles to enhance adhesion, hydrophobicity, or reactivity. Serves as an intermediate in the production of silane coupling agents for composites, adhesives, and coatings. Its bromoalkyl functionality allows further chemical derivatization through nucleophilic substitution reactions, making it valuable in organic and polymer chemistry. Handle with care due to moisture sensitivity and potential corrosivity.
