Description

4-Bromophenylmethyldichlorosilane is a versatile organosilicon reagent featuring both a reactive dichlorosilyl group and a brominated aromatic ring. This bifunctional structure makes it a critical intermediate for synthesizing advanced silicone polymers and functionalized silane coupling agents. It is essential for R&D and production in the pharmaceutical, agrochemical, and advanced materials sectors, where precise molecular modification is required.

Application

• Silane Coupling Agent Precursor: Used to synthesize specialized silanes for surface modification of glass, silica, and other inorganic fillers to enhance composite material performance.
• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, particularly those requiring silicon-containing or bromoaryl motifs.
• Agrochemical Synthesis: Employed in the production of advanced pesticides and herbicides, where the bromophenyl group can be further functionalized.
• Polymer & Resin Modification: Acts as a monomer or cross-linking agent in the manufacture of heat-resistant and chemically stable silicone resins and specialty polymers.
• Surface-Initiated Polymerization: Utilized to create self-assembled monolayers (SAMs) or initiator layers on substrates for controlled polymer growth in nanotechnology applications.
• Liquid Crystal & OLED Materials: Functions as a synthetic intermediate for silicon-based components in electronic display and lighting technologies.

Quality Control

Our 4-Bromophenylmethyldichlorosilane is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including GC, NMR, and titration methods, to ensure high purity and consistency. A Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to guarantee compliance with your research and production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Keep away from strong acids and organic solvents.
