Description

Methyl 11-(Dichloromethylsilyl)Undecanoate is a specialized organosilicon ester compound that serves as a key intermediate in advanced material synthesis. This bifunctional molecule is valued for its ability to act as a coupling agent, bridging organic polymers with inorganic substrates to enhance material properties. It is primarily sought by R&D and production teams in the silicone polymer, surface coating, and adhesive industries for developing high-performance, functionalized materials.

Application

• Silicone Polymer Modification: Acts as a functional monomer or cross-linking agent to introduce long alkyl chains and reactive silyl groups into silicone backbones, modifying flexibility and surface properties.
• Surface Coupling Agent: Used to promote adhesion between organic resins (e.g., epoxies, polyurethanes) and inorganic surfaces like glass, metals, or minerals in composite materials and coatings.
• Hydrophobic Coating Formulation: A key precursor for creating water-repellent and release coatings on textiles, paper, and construction materials.
• Adhesive and Sealant Additive: Incorporated to improve moisture-curing characteristics, adhesion strength, and durability in high-performance sealants and adhesives.
• Research & Development: Serves as a valuable building block in academic and industrial R&D for synthesizing novel organosilicon compounds and hybrid materials.
• Lubricant and Grease Additive: Potential use as a functional additive to enhance the thermal stability and surface affinity of synthetic lubricants.

Quality Control

Our production of Methyl 11-(Dichloromethylsilyl)Undecanoate adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and reacts with strong acids/organic solvents; therefore, it must be kept under an inert atmosphere (e.g., nitrogen or argon) in its original sealed packaging to prevent degradation. Keep away from incompatible materials.
