Description

(Chloromethyl)Decyldimethylsilane is a high-purity organosilicon compound featuring a reactive chloromethyl group and a long decyl chain. This unique structure makes it a valuable intermediate for introducing hydrophobic and organofunctional properties into materials. It is primarily used by R&D chemists and process engineers in the silicone, polymer, and surface modification industries for creating advanced functional materials.

Application

• Silicone Modification: Key intermediate for synthesizing specialty silicone oils, resins, and elastomers with enhanced hydrophobicity and specific functional groups.
• Surface Treatment Agent: Used to create hydrophobic, oleophobic, or release coatings on glass, metals, and polymers for industrial and electronic applications.
• Coupling Agent: Acts as a molecular bridge to improve adhesion between organic polymers and inorganic substrates like silica or minerals in composite materials.
• Pharmaceutical & Agro-Intermediate: Serves as a building block in the synthesis of more complex molecules for pharmaceutical active ingredients or agrochemicals.
• Polymer Functionalization: Employed to graft functional side chains onto polymer backbones, altering physical properties like solubility, thermal stability, or reactivity.
• Research & Development: A versatile reagent in organic and materials chemistry labs for developing novel silicon-based compounds and exploring new material properties.

Quality Control

Every batch of (Chloromethyl)Decyldimethylsilane is manufactured and tested under strict quality management protocols to ensure consistency and purity for your synthesis. Our products undergo rigorous quality testing, including GC, NMR, and Karl Fischer titration, to ensure compliance with industry standards. Certificates of Analysis (COA) detailing purity and impurity profiles are available upon request.

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). This compound is hygroscopic (moisture-sensitive); containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
