Description

11-Bromo-1-undecene is a versatile, high-purity organic intermediate featuring a terminal alkene and a bromoalkyl chain. This bifunctional structure makes it a critical building block for synthesizing complex molecules through cross-coupling and functional group transformations. It is essential for R&D chemists and process engineers in the pharmaceutical, agrochemical, and advanced materials sectors seeking to introduce long-chain functionalities or create novel macrocyclic compounds.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly for introducing long alkyl chains or as a precursor for macrocyclic lactams and lactones.
• Agrochemical Synthesis: Serves as a key intermediate for producing crop protection agents, surfactants, and plant growth regulators.
• Polymer & Material Science: Acts as a monomer or cross-linking agent in the production of specialty polymers, liquid crystals, and surface-modifying agents.
• Organic Synthesis Building Block: Utilized in Heck reactions, Grignard reactions, and other cross-coupling methodologies to construct complex organic frameworks.
• Lubricant & Fuel Additive Precursor: Employed in the manufacture of high-performance additives that improve viscosity and stability.
• Fragrance & Flavor Chemistry: Used as a synthetic intermediate for musk fragrances and other long-chain aroma chemicals.
