Description

Cyanopropyl Dimethyl Dimethylamino Silane is a specialized organosilicon compound featuring a reactive dimethylamino group and a cyano-functional propyl chain. This unique bifunctional structure makes it a valuable intermediate for introducing both amino and cyano functionalities onto surfaces or into polymer matrices. It is primarily utilized in the production of advanced materials, including specialty silicones, surface modifiers, and chromatographic stationary phases. Industries such as pharmaceuticals, analytical chemistry, and high-performance materials rely on this silane for its precise reactivity and ability to tailor surface properties.

Application

• Surface Modification Agent: Used to functionalize silica, glass, and other inorganic surfaces for improved adhesion, wettability, or specific chemical binding in composite materials and coatings.
• Intermediate for Specialty Silicones: Serves as a key building block in the synthesis of custom silicone oils, resins, and elastomers with specific polar or reactive end groups.
• Chromatography Stationary Phases: Employed in the derivatization of silica gel to create cyanopropyl-bonded phases for High-Performance Liquid Chromatography (HPLC), particularly useful for separating polar compounds.
• Adhesion Promoter: Enhances the bond between organic polymers and inorganic substrates in sealants, adhesives, and electronic encapsulants.
• Pharmaceutical Intermediate: Acts as a reagent in the synthesis of drug molecules or drug delivery systems where its functional groups can be further elaborated.
• Research & Development: Utilized in academic and industrial R&D for developing novel functional materials, sensors, and catalysts.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and batch-to-batch consistency. Standard quality control includes verification of identity, purity, and key physical parameters. Certificates of Analysis (COA) detailing specific test results are available upon request for every batch shipped. We adhere to strict internal quality management protocols to meet the high-purity requirements of our global customer base in research and manufacturing.

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). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from strong acids and oxidizing agents.
