Description

4-(3-Bromophenyl)But-1-Ene is a valuable brominated aromatic building block featuring a terminal alkene functional group. This unique structure makes it a versatile intermediate for synthesizing more complex molecules through cross-coupling and olefin metathesis reactions. It is primarily sought after by research chemists and process development scientists in the pharmaceutical and advanced materials sectors for constructing novel chemical entities and functional polymers.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, particularly those requiring a brominated phenyl moiety.
• Organic Synthesis Building Block: Utilized in Heck reactions, Suzuki-Miyaura cross-couplings, and other palladium-catalyzed transformations to introduce the 3-bromophenyl group into target molecules.
• Material Science Research: Acts as a monomer or co-monomer in the development of specialty polymers and liquid crystals, leveraging its aromatic core and polymerizable alkene group.
• Agrochemical Synthesis: Employed in the research and development of novel herbicides, fungicides, and plant growth regulators.
• Ligand and Catalyst Development: Used to create novel phosphine or N-heterocyclic carbene (NHC) ligands for asymmetric catalysis.
• Chemical Biology Probes: Functions as a starting material for synthesizing fluorescent tags or photoaffinity labels for studying biological systems.
