Applicazioni

4-Bromostyrene is widely utilized in the synthesis of nitroolefins by alkene cross-metathesis. It plays an important role in the Heck reaction to the synthesis of poly(1,4-phenylenevinylene). It is employed in the structure activity relationships (SAR) study of the chemical and biochemical properties of the vinyl group of styrene. It is also used to investigate the photochemical growth of Br-terminated self-assembled monolayers. It is also involved in the synthesis of silsesquioxanes.

Note

Store in a cool place. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with acids, bases, oxidizing agents and halogens. Keep away from sources of ignition.
