Description

[(Z)-2-Bromoethenyl]Benzene CAS NO 588-73-8 is a high-purity, light-sensitive organobromine compound that serves as a versatile and critical building block in advanced organic synthesis. Its unique structure, featuring a bromine atom adjacent to a vinyl group attached to a benzene ring, makes it an essential reagent for introducing the styryl moiety and for participating in cross-coupling reactions. This intermediate is particularly valuable for research and development chemists and process engineers in the pharmaceutical, agrochemical, and specialty chemical industries who require reliable, high-quality raw materials for creating complex molecular architectures.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds containing styrene or substituted styrene frameworks.
• Agrochemical Synthesis: Used in the development of novel pesticides, herbicides, and fungicides where the bromovinyl group acts as a reactive handle for further functionalization.
• Material Science & Liquid Crystals: Serves as a building block for organic electronic materials, ligands for catalysts, and components in liquid crystal displays (LCDs).
• Cross-Coupling Reactions: An effective substrate in Heck, Suzuki, and Stille cross-coupling reactions to form new carbon-carbon bonds, essential for constructing complex organic molecules.
• Polymer Chemistry: Can be utilized as a monomer or co-monomer in the synthesis of specialized polymers with unique optical or electronic properties.
• Organic Synthesis & Research: A valuable reagent for academic and industrial R&D laboratories exploring new synthetic methodologies and creating novel chemical entities.
