Description

Dichloroisobutylmethylsilane is a highly reactive organosilicon compound, also known as CAS NO 18028-96-1, that serves as a critical building block in advanced material synthesis. Its value lies in its bifunctional chlorosilane structure, enabling precise surface modification and the creation of tailored silicone polymers. This chemical is essential for manufacturers and R&D facilities in the silicone, pharmaceutical, and specialty chemical industries seeking to develop high-performance materials with specific hydrophobic or coupling properties.

Application

• Silicone Intermediate: A key precursor in the synthesis of custom silicone fluids, resins, and elastomers.
• Surface Modification Agent: Used to impart hydrophobic or release properties to inorganic surfaces like silica, glass, and metals.
• Coupling Agent: Enhances adhesion between organic polymers and inorganic fillers in composite materials.
• Pharmaceutical Synthesis: Serves as a protecting group or intermediate in the synthesis of complex drug molecules and active pharmaceutical ingredients (APIs).
• Crosslinking Agent: Employed in formulations for room-temperature vulcanizing (RTV) silicones and sealants.
• Chemical Vapor Deposition (CVD): A potential source for depositing silicon-containing thin films on substrates.
• Laboratory Reagent: Used in research for introducing the isobutylmethylsilyl group into organic molecules.

Quality Control

Our Dichloroisobutylmethylsilane is produced under stringent quality management protocols. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) for purity and identity verification, to ensure it meets exacting standards for consistency and performance. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee supply reliability and technical compliance for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and hygroscopic (moisture-sensitive) 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 maximize stability. Keep away from moisture, heat, and incompatible materials such as strong bases, acids, and oxidizing agents.
