Description

Chlorodimethylisobutylsilane is a versatile organosilicon compound, specifically a chlorosilane, that serves as a key intermediate in the synthesis of functional silanes and silicone polymers. Its value lies in its reactive chlorosilane group, which readily undergoes hydrolysis, condensation, and other coupling reactions to introduce the isobutyl-dimethylsilyl moiety into target molecules. This product is essential for manufacturers and R&D teams in the silicone, pharmaceutical, and advanced materials sectors seeking to modify surfaces, create custom silane coupling agents, or build specialized organosilicon architectures.

Application

• Silane Coupling Agent Precursor: Used to synthesize custom silane coupling agents for improving adhesion between organic polymers and inorganic surfaces like glass, minerals, or metals.
• Silicone Polymer Modification: Serves as a reactive monomer or end-capping agent in the production of specialty silicone oils, resins, and elastomers, imparting hydrophobic isobutyl groups.
• Surface Hydrophobization: Applied to treat surfaces such as silica, nanoparticles, or textiles to create water-repellent (hydrophobic) coatings.
• Pharmaceutical & Agrochemical Intermediates: Utilized in organic synthesis to introduce silyl protecting groups for sensitive functional groups during complex molecule manufacturing.
• Crosslinking Agent: Acts as a crosslinker in silicone sealants and room-temperature-vulcanizing (RTV) rubbers to enhance mechanical properties.
• Research & Development: A valuable building block in academic and industrial R&D for developing new organosilicon compounds, catalysts, and functional materials.

Quality Control

Our Chlorodimethylisobutylsilane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) for purity and identity confirmation, to ensure it meets precise specifications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee supply consistency and reliability for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat and ignition sources. Due to its hygroscopic and moisture-sensitive 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 extended shelf life. Keep away from strong acids, bases, and oxidizing agents.
