Description

2-Cyanoethylmethyldichlorosilane is a highly reactive organosilicon compound that serves as a crucial building block in advanced material synthesis. Its value lies in its dual functionality, featuring both a reactive dichlorosilane group and a cyanoethyl moiety, enabling the creation of specialized silicone polymers and surface modifiers. This chemical is essential for manufacturers and R&D teams in the electronics, specialty polymer, and advanced coatings industries seeking to develop materials with tailored surface properties and enhanced performance characteristics.

Application

• Silicone Polymer Modification: Acts as a key monomer or cross-linking agent for introducing cyano-functional groups into silicone resins and rubbers, enhancing their polarity and adhesion properties.
• Surface Treatment & Coupling Agent: Used to modify inorganic surfaces like glass, silica, and metals, creating a hydrophobic or organofunctional layer that improves compatibility with organic matrices in composite materials.
• Electronic Encapsulants & Sealants: Incorporated into formulations for potting compounds and sealants in electronics to provide moisture resistance and stable dielectric properties.
• Intermediate for Specialty Silanes: Serves as a precursor for synthesizing more complex silane coupling agents and functionalized siloxanes used in advanced industrial applications.
• Research & Development: A valuable reagent in academic and industrial R&D labs for exploring new organosilicon chemistry, novel polymer architectures, and nanotechnology applications.

Quality Control

Every batch of 2-Cyanoethylmethyldichlorosilane is produced and tested under stringent quality management protocols to ensure consistency and reliability for industrial applications. Our standard grade meets high-purity specifications critical for synthesis and formulation processes. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, acids, and oxidizing agents.
