Description

4-Bromophenyldimethylchlorosilane is a versatile organosilicon reagent featuring both a reactive chlorosilyl group and a brominated aromatic ring. This bifunctional nature makes it a critical building block for introducing silyl protecting groups and creating advanced silicon-based materials. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries who require precise molecular modification and surface functionalization.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and complex molecules, often serving as a silylating agent or a precursor for more elaborate silicon-containing structures.
• Agrochemical Synthesis: Acts as a key reagent in creating novel pesticides, herbicides, and plant growth regulators that incorporate silicon for enhanced stability or bioavailability.
• Surface Modification & Silane Coupling Agent: Functionalizes inorganic surfaces like silica, glass, or metals to improve adhesion, dispersion, or compatibility in composite materials and coatings.
• Polymer & Material Science: Serves as a monomer or cross-linking agent in the production of specialty silicones, siloxane-based polymers, and advanced hybrid organic-inorganic materials.
• Liquid Crystal & OLED Materials: Employed in the synthesis of silicon-based components for electronic displays and optoelectronic devices due to its ability to modify molecular architecture and properties.
• Protecting Group Chemistry: The chlorosilyl group is effective for temporarily protecting hydroxyl groups during multi-step synthetic sequences in organic chemistry.

Quality Control

Our 4-Bromophenyldimethylchlorosilane is produced under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including GC, NMR, and titration, to ensure high purity and consistency. A Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee it meets your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) and away from moisture. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, alcohols, and oxidizing agents.
