Description

2-Bromoethyltrichlorosilane is a versatile organosilicon reagent featuring both a reactive bromoalkyl group and hydrolyzable trichlorosilyl functionality. This dual reactivity makes it a critical intermediate for introducing silicon-containing moieties into organic frameworks and for surface modification. It is essential for R&D and production in advanced material science and fine chemical synthesis. Key industries that rely on this compound include pharmaceuticals, semiconductors, and specialty polymers.

Application

• Surface Modification Agent: Used as a coupling agent to functionalize glass, silica, and other inorganic surfaces for improved adhesion and compatibility in composite materials.
• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of active pharmaceutical ingredients (APIs) and silicon-based drug candidates.
• Polymer & Resin Synthesis: Employed as a monomer or cross-linking agent in the production of silicone resins, hybrid organic-inorganic polymers, and specialty coatings.
• Semiconductor Manufacturing: Utilized in chemical vapor deposition (CVD) processes to create thin films and dielectric layers on silicon wafers.
• Adhesive & Sealant Formulations: Acts as an adhesion promoter, enhancing the bond strength and durability of silicone-based adhesives and sealants.
• Chemical Research (R&D): A valuable reagent for developing novel organosilicon compounds, dendrimers, and functional materials in academic and industrial laboratories.

Quality Control

Our 2-Bromoethyltrichlorosilane is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC, NMR, and titration methods, to ensure high purity and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all relevant specifications. Our quality commitment ensures the material meets the stringent requirements for research and industrial applications.

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 must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Recommended storage temperature is 2-8°C for long-term stability. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents.
