Description

11-(Trimethylsilyloxy)Undecyl Bromide is a bifunctional organosilicon compound featuring a terminal bromoalkyl chain and a silyl-protected hydroxyl group. This unique structure makes it a versatile intermediate for the synthesis of functionalized polymers, surfactants, and complex organic molecules. It is primarily utilized by researchers and manufacturers in the pharmaceutical, advanced materials, and specialty chemical sectors for creating novel compounds with tailored surface properties and reactivity.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, particularly where a long-chain hydrophobic linker is required.
• Surface Modification Agent: Acts as a key reagent for introducing hydrophobic, self-assembling monolayers (SAMs) onto silicon, glass, or metal oxide surfaces.
• Polymer & Dendrimer Synthesis: Serves as a functional monomer or chain extender in the production of specialty silicones, block copolymers, and dendritic structures.
• Liquid Crystal & Display Technology: Employed as a precursor for mesogenic compounds and alignment layers in liquid crystal displays (LCDs).
• Crosslinking Agent: Utilized in the formulation of high-performance silicone elastomers and resins to enhance mechanical properties.
• Surfactant & Detergent Chemistry: Functions as a precursor for synthesizing novel silicone-based surfactants with unique emulsifying properties.
