Description

Bis(Cyanopropyl)Dichlorosilane is a highly reactive organosilicon compound that serves as a critical intermediate in the synthesis of advanced silicone materials. Its dual functional groups—chlorosilane and nitrile—make it a versatile building block for introducing specific properties into polymers and surfaces. This product is essential for manufacturers in the specialty chemicals, electronics, and advanced materials sectors seeking to develop custom silane coupling agents, hydrophobic coatings, and functionalized silicones.

Application

• Silane Coupling Agent Precursor: A key intermediate for synthesizing specialized silane coupling agents used to improve adhesion between organic polymers and inorganic surfaces like glass, metals, and minerals.
• Functionalized Silicone Synthesis: Used to incorporate cyanoalkyl functional groups into silicone polymers, modifying their surface energy, reactivity, and compatibility with other materials.
• Hydrophobic & Oleophobic Coatings: Serves as a building block for creating surface treatments that impart water and oil repellency to textiles, paper, and electronic components.
• Adhesive & Sealant Formulations: Enhances the performance of high-strength adhesives and sealants by improving substrate wetting and chemical resistance.
• Electronic Encapsulants: Used in the production of silicones for potting and encapsulating sensitive electronic devices, where moisture resistance and thermal stability are critical.
• Chromatography Stationary Phases: A starting material for derivatizing silica gel to create specialized phases for analytical and preparative chromatography.
• Research & Development: Employed in academic and industrial R&D for exploring new organosilicon chemistry, novel polymer architectures, and advanced material properties.

Quality Control

Our production of Bis(Cyanopropyl)Dichlorosilane adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including gas chromatography (GC) for assay and impurity profiling, to meet exacting customer specifications. Certificates of Analysis (COA) detailing all critical parameters are provided with every 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, well-ventilated area at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and reacts vigorously with water, strong acids, and bases. Containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Keep away from heat, sparks, and open flame.
