Description

13-(Chlorodimethylsilylmethyl)-Heptacosane CAS NO 194243-00-0 is a specialized organosilicon compound featuring a long-chain heptacosane backbone terminated with a reactive chlorodimethylsilyl group. This unique structure makes it a valuable intermediate for introducing hydrophobic, long-chain alkyl groups onto surfaces or into polymer matrices, significantly modifying surface energy and compatibility. It is primarily needed by R&D chemists and material scientists in the advanced materials, specialty coatings, and silicone modification sectors for developing novel functional materials.

Application

• Surface Modification Agent: Used to create hydrophobic, low-surface-energy coatings on glass, metals, and ceramics for anti-fouling, water-repellent, or easy-clean applications.
• Silicone Polymer Modifier: Acts as a functional monomer or chain extender to incorporate long alkyl chains into polysiloxanes, tailoring their rheological properties, solubility, and compatibility with organic systems.
• Adhesion Promoter & Coupling Agent: Enhances the interfacial adhesion between inorganic fillers (like silica) and organic polymer matrices in composite materials, improving mechanical properties.
• Lubricant & Release Agent Intermediate: Serves as a precursor for synthesizing high-performance silicone-based lubricants and mold release agents with enhanced thermal stability and slip properties.
• Research & Development: A key building block in organic and polymer chemistry research for constructing complex molecular architectures with specific surface-active characteristics.

Quality Control

Our 13-(Chlorodimethylsilylmethyl)-Heptacosane is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including GC, NMR, and FTIR to confirm identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and physical properties is provided with every shipment to support your quality assurance processes.

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 hydrolysis and maintain product integrity.
