Description

4-Bromo-2-Hexene is a versatile halogenated alkene intermediate with significant utility in synthetic organic chemistry. Its primary value lies in its reactivity as an electrophile and as a building block for constructing more complex molecules through cross-coupling and addition reactions. This compound is essential for researchers and process chemists in the pharmaceutical, agrochemical, and advanced materials sectors who require high-purity intermediates for fine chemical synthesis.

Application

• As a key electrophilic intermediate in palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Heck, Stille) for carbon-carbon bond formation.
• Utilized in the synthesis of pharmaceutical active ingredients (APIs) and complex natural product analogs.
• Acts as a precursor in the development of agrochemicals, including herbicides and insecticides.
• Serves as a monomer or modifier in the research and production of specialty polymers and functional materials.
• Employed in academic and industrial R&D for methodological studies in organic synthesis.
• Used to introduce the hexenyl moiety into target molecules for flavor and fragrance ingredient synthesis.

Quality Control

Our 4-Bromo-2-Hexene is produced and handled under a strict quality management system. Every batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopy (NMR, IR), to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all critical parameters are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and bases. Recommended storage temperature is 2-8°C for extended stability. Keep container tightly sealed when not in use to prevent moisture ingress and volatility loss.
