Description

Trimethyl[[2,2',5,5'-Tetrachloro(1,1'-Biphenyl)-4-Yl]Oxy]Silane is a specialized organosilicon derivative of a polychlorinated biphenyl (PCB) core, designed for advanced material synthesis. This compound is valued for its ability to act as a versatile silylating agent and a key synthetic intermediate, introducing both silicon functionality and a halogenated aromatic moiety into target molecules. It is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and advanced polymer industries for developing novel compounds with tailored properties.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly for introducing the silyl-protected biphenyl group into complex molecular architectures.
• Agrochemical Synthesis: Serves as a key building block for creating novel herbicides, fungicides, and insecticides with enhanced stability and efficacy.
• Material Science & Polymer Chemistry: Employed as a monomer or cross-linking agent in the development of specialty silicones, liquid crystal polymers, and high-performance resins.
• Surface Modification Agent: Used to functionalize silica, glass, or other inorganic surfaces, imparting specific hydrophobic or chemical properties.
• Organic Synthesis Reagent: Acts as a protective group for alcohols and phenols or as a precursor for further coupling reactions (e.g., Suzuki, Stille) via its halogenated aromatic ring.
• Research & Development: A valuable tool in academic and industrial R&D for exploring new organosilicon chemistry and creating novel chemical entities.
