Description

1-Bromo-1-Cyclopentene CAS NO 1192-04-7 is a versatile halogenated olefin building block, prized for its reactive bromine substituent on a strained cyclic alkene. This unique structure makes it a critical intermediate for synthesizing complex organic molecules, particularly in the pharmaceutical and agrochemical sectors. It is essential for researchers and manufacturers engaged in cross-coupling reactions, cycloadditions, and the development of novel active ingredients.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), especially those containing cyclopentane or modified ring systems.
• Agrochemical Synthesis: Used in the production of advanced pesticides, herbicides, and fungicides where the bromocyclopentene moiety introduces specific biological activity.
• Organic Synthesis & Research: A valuable reagent for Suzuki, Heck, and other palladium-catalyzed cross-coupling reactions to form carbon-carbon bonds.
• Material Science Precursor: Serves as a monomer or functionalization agent in the development of specialty polymers and advanced materials.
• Fine Chemical Production: Employed in the manufacture of flavors, fragrances, and other high-value specialty chemicals.
