Description

(3,3-Dimethylbutyl)Dimethylchlorosilane is a highly reactive organosilicon compound, specifically a chlorosilane, used as a key intermediate in organic synthesis and materials science. Its primary value lies in its ability to introduce the bulky (3,3-dimethylbutyl) group onto silicon-based polymers and surfaces, modifying properties like hydrophobicity and thermal stability. This chemical is essential for researchers and manufacturers in the silicone industry, advanced polymer development, and surface modification technologies.

Application

• Silicone Polymer Modification: Acts as a functional monomer or chain terminator to create custom silicone oils, rubbers, and resins with specific side-chain properties.
• Surface Silylation Agent: Used to hydrophobically modify inorganic surfaces (e.g., silica, glass) for applications in chromatography, composites, and coatings.
• Pharmaceutical & Agro-Intermediate: Serves as a building block for synthesizing more complex organosilicon molecules with potential biological activity.
• Adhesion Promoter Precursor: A key raw material in the synthesis of silane coupling agents for improving adhesion between organic polymers and inorganic materials.
• Specialty Silicone Fluids: Employed in the production of high-performance lubricants and heat transfer fluids with enhanced stability.
• Research & Development: A valuable reagent in academic and industrial R&D for exploring new organosilicon chemistry and material properties.

Quality Control

Our (3,3-Dimethylbutyl)Dimethylchlorosilane is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including GC (Gas Chromatography) for purity and identity confirmation, to ensure it meets high-purity standards suitable for demanding applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and moisture-sensitive (hygroscopic) nature, this material must be stored under a dry, inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated area. Recommended storage temperature is 2-8°C to minimize degradation and maintain stability. Keep away from moisture, bases, and oxidizing agents.
