Description

(Bromomethyl)Silane CAS NO 7570-21-0 is a versatile organosilicon reagent featuring a reactive bromomethyl group directly bonded to a silicon atom. This unique structure makes it a critical building block for introducing functional silane groups into more complex organic and polymeric architectures. It is essential for researchers and manufacturers in advanced material science and fine chemical synthesis who require precise molecular modification. Its primary value lies in enabling the creation of tailored silicon-containing compounds with specific properties.

Application

• Surface Modification Agent: Used to functionalize silica, glass, and other inorganic surfaces to alter wettability, adhesion, or introduce reactive sites.
• Polymer & Resin Synthesis: Serves as a monomer or cross-linking agent in the production of specialty silicones, siloxane-based polymers, and hybrid organic-inorganic materials.
• Pharmaceutical Intermediates: Acts as a key synthon in the multi-step synthesis of silicon-containing drug candidates and active pharmaceutical ingredients (APIs).
• Adhesive & Sealant Formulations: Incorporated as an adhesion promoter or curing agent in high-performance silicone-based adhesives and sealants.
• Coupling Agent for Composites: Enhances the interface between organic polymers and inorganic fillers (like glass fibers or minerals) in composite materials.
• Lithography & Semiconductor Processing: Utilized in the development of silicon-based precursors for photoresists and thin-film deposition in microelectronics.
• Laboratory Reagent: Employed in organic synthesis research for nucleophilic substitution reactions and the construction of organosilicon frameworks.

Quality Control

Our (Bromomethyl)Silane is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay (GC), purity verification, and identity confirmation. A detailed Certificate of Analysis (COA) documenting all test results is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its moisture-sensitive (hygroscopic) nature, containers should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use to prevent decomposition. Recommended storage temperature is 2-8°C for extended stability.
