Used primarily as a monomer in polymer chemistry, enabling the synthesis of functional polystyrene derivatives with tailored properties. Its bromine functionality allows for further chemical modifications through cross-coupling reactions such as Suzuki or Heck reactions, making it valuable in the development of advanced organic materials. Commonly employed in the preparation of cross-linked resins for solid-phase synthesis and chromatographic supports. Also utilized in the fabrication of optoelectronic materials and conjugated polymers due to its ability to participate in controlled polymerization techniques. Its reactivity makes it suitable for surface functionalization and grafting onto various substrates for specialized coatings and sensors.
