Description

Butenylmethyldichlorosilane is a highly reactive organosilicon compound, specifically a chlorosilane, that serves as a crucial intermediate in the synthesis of advanced silicone polymers and functional materials. Its value lies in the unique combination of the butenyl group, offering potential for further chemical modification, and the dichlorosilane functionality, which readily undergoes hydrolysis and condensation reactions. This product is essential for R&D chemists and manufacturers in the silicone, specialty polymer, and surface treatment industries seeking to develop novel materials with tailored properties.

Application

• Silicone Polymer Synthesis: A key monomer or intermediate for producing modified silicone oils, resins, and elastomers with specific organic side chains.
• Surface Modification Agent: Used to impart hydrophobic or oleophobic properties to inorganic surfaces like glass, silica, or metals via silanization.
• Coupling Agent/Crosslinker: Functions as a bridging molecule in composite materials to improve adhesion between organic polymers and inorganic fillers.
• Pharmaceutical & Agro-chemical Intermediates: Serves as a building block in the synthesis of more complex organosilicon molecules for specialized applications.
• Research & Development: Utilized in academic and industrial labs for developing new silicone-based materials, coatings, and release agents.
• Precursor for Silane Functionalization: The dichloro groups can be substituted to create other functional silanes, such as alkoxysilanes or aminosilanes.

Quality Control

Our Butenylmethyldichlorosilane is produced under stringent process controls to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including gas chromatography (GC) for assay and impurity profiling. Certificates of Analysis (COA) detailing purity, identity, and specific test results are provided with every shipment and are available upon request to support your quality assurance protocols.

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 minimize volatility and degradation. Keep away from heat, sparks, open flames, and incompatible materials such as water, strong bases, and oxidizing agents.
