Description

4-Bromophenyldimethylsilane is a versatile organosilicon compound featuring a brominated aromatic ring, making it a valuable synthon for advanced material science and pharmaceutical chemistry. Its core value lies in its dual functionality, serving as both a protected silane precursor and a reactive aryl halide for cross-coupling reactions. This product is essential for R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries who require high-purity intermediates for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for Suzuki-Miyaura and other palladium-catalyzed cross-coupling reactions.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides where the bromophenyl moiety is incorporated into the final active molecule.
• Material Science Precursor: Serves as a monomer or grafting agent in the production of functionalized silicones, silsesquioxanes, and other advanced polymeric materials.
• Liquid Crystal & OLED Materials: Employed in the synthesis of organosilicon components for electronic displays and organic light-emitting diodes due to its stable aromatic system.
• Surface Modification Agent: Used to functionalize silica, glass, or metal oxide surfaces, imparting specific hydrophobic or reactive properties.
• Laboratory Reagent: A valuable reagent in academic and industrial research for exploring new organometallic and silicon chemistry.

Quality Control

Our 4-Bromophenyldimethylsilane is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high chemical purity and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment, ensuring full traceability and compliance with your internal quality standards.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place at 15-25°C. Keep away from heat, sparks, and open flames. For long-term storage under an inert atmosphere (e.g., nitrogen or argon), please contact our technical team for specific recommendations.
