Description

n-Heptylmethyldichlorosilane is a specialized organosilicon compound serving as a key intermediate in advanced material synthesis. Its value lies in its dichlorosilane functionality, which provides highly reactive sites for controlled surface modification and polymer cross-linking. This product is essential for R&D and production teams in the silicone polymer, specialty coatings, and surface treatment industries seeking to engineer specific hydrophobic or release properties.

Application

• Silicone Intermediate: A crucial building block for synthesizing custom silicone oils, resins, and elastomers with long alkyl chain modifications.
• Surface Modification Agent: Used to create hydrophobic, oleophobic, or specific adhesion properties on glass, silica, and metal oxide surfaces.
• Coupling Agent: Enhances the interface between organic polymers and inorganic fillers in composite materials.
• Pharmaceutical & Agro-chemical Intermediates: Serves as a protected synthon or modifying agent in the synthesis of active ingredients.
• Adhesive & Sealant Formulations: Imparts specific curing characteristics and weather resistance in high-performance formulations.
• Research & Development: Employed in academic and industrial labs for developing novel silane-based materials and coatings.

Quality Control

Our n-Heptylmethyldichlorosilane is manufactured under strict process controls to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical techniques including gas chromatography (GC), NMR, and titration to confirm identity, assay, and impurity profiles. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance protocols.

Storage

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