Description

11-Bromoundecanoic Acid Trimethylsilyl Ester is a high-purity organosilicon intermediate featuring a reactive bromoalkyl chain. This compound is valued for its dual functionality, serving as a versatile building block in advanced organic synthesis and materials science. It is primarily sought by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Key synthon for the preparation of long-chain fatty acid analogs, prodrugs, and bioactive molecules.
• Surface Modification Agent: Used to introduce hydrophobic trimethylsilyl groups or reactive bromo-terminated chains onto silica, polymers, or nanoparticles.
• Polymer Chemistry: Serves as a monomer or chain-transfer agent in the synthesis of functionalized polymers and silicone-based copolymers.
• Liquid Crystal & OLED Materials: A precursor for synthesizing alkyl-bridged mesogenic compounds and organic electronic materials.
• Cross-coupling Reactions: The bromine atom is amenable to palladium-catalyzed reactions like Suzuki, Heck, or Negishi couplings for carbon-carbon bond formation.
• Organic Synthesis Reagent: Used as a protected carboxylic acid derivative with a latent alkyl halide functionality for multi-step syntheses.
