Description

3-Cyanopropylphenyldichlorosilane is a versatile organosilicon reagent featuring both a reactive dichlorosilane group and a cyano-functionalized propyl chain. This bifunctional nature makes it a critical intermediate for introducing silane linkages and pendant nitrile groups into advanced materials. It is essential for manufacturers and R&D teams in the silicone polymer, surface modification, and specialty chemical synthesis sectors seeking to create custom siloxane architectures or functionalized surfaces.

Application

• Silicone Polymer Modification: Serves as a key monomer or cross-linker for synthesizing specialty cyano-functionalized polysiloxanes with tailored properties.
• Surface Priming Agent: Used to treat glass, silica, and metal oxide surfaces to create a covalently bonded organic layer with terminal nitrile groups for further chemical attachment.
• Chromatography Stationary Phases: Employed in the derivatization of silica gel to produce cyano-propyl bonded phases for HPLC and solid-phase extraction.
• Adhesive & Sealant Formulations: Imparts adhesion promotion and moisture-curing characteristics in high-performance silicone-based systems.
• Intermediate for Further Synthesis: The nitrile group can be hydrolyzed to carboxylic acid or reduced to amine, enabling the synthesis of a wide range of functional silanes.
• Nanomaterial Functionalization: Used to graft functional organic layers onto nanoparticles (e.g., silica, quantum dots) for dispersion control and specific reactivity.

Quality Control

Our production of 3-Cyanopropylphenyldichlorosilane adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including GC, NMR, and titration methods, to ensure high purity and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed specifications. We operate under a quality system designed to meet the demands of industrial and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Recommended storage temperature is 2-8°C for long-term stability. Keep away from strong acids, bases, and oxidizing agents.
