Description

(3-Cyanobutyl)Methyldichlorosilane is a specialized organosilicon compound featuring both a reactive dichlorosilane group and a cyano-functionalized alkyl chain. This dual functionality makes it a valuable intermediate for the synthesis of advanced silicone polymers and surface-modifying agents. It is primarily utilized by manufacturers in the silicone, pharmaceutical, and advanced materials industries seeking to incorporate polar nitrile groups into siloxane backbones or surfaces.

Application

• Silicone Polymer Modification: Serves as a key monomer or chain extender for introducing polar cyano groups into polydimethylsiloxane (PDMS) polymers, enhancing their compatibility with polar substrates and solvents.
• Surface Coupling Agent: Used to modify inorganic surfaces like glass, silica, or metals, creating a covalently bonded organic layer with terminal nitrile functionality for further chemical reactions or improved adhesion.
• Pharmaceutical Intermediates: Acts as a building block in the synthesis of silicon-containing drug candidates or diagnostic agents, where the cyano group can be transformed into other functional groups like carboxylic acids or tetrazoles.
• Specialty Resins & Elastomers: Employed in the production of high-performance silicone resins and elastomers with tailored properties such as increased thermal stability, chemical resistance, or specific dielectric characteristics.
• Adhesive & Sealant Formulations: Incorporated as an adhesion promoter in silicone-based adhesives and sealants to improve bonding to difficult substrates.
• Research & Development: A valuable reagent for academic and industrial R&D in organosilicon chemistry, materials science, and polymer synthesis.

Quality Control

Our production of (3-Cyanobutyl)Methyldichlorosilane adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing, including GC, NMR, and titration methods, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and reacts with strong acids and bases. Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and maintain product integrity.
