Description

Octyloxydimethylsilyl Chloride is a versatile organosilicon reagent featuring a reactive chlorosilyl group and a hydrophobic octyloxy chain. This compound is essential for introducing surface-modifying silyl groups onto inorganic substrates or organic polymers, imparting water-repellent and release properties. It is a critical intermediate for manufacturers in the silicone, pharmaceutical, and advanced materials sectors seeking to engineer specific surface characteristics and reactivity.

Application

• Surface Modification Agent: Key for hydrophobization and functionalization of silica, glass, and metal oxide surfaces.
• Silicone Intermediate: Used in the synthesis of specialty silicone oils, resins, and elastomers with tailored properties.
• Coupling Agent: Acts as a linker to improve adhesion between organic polymers and inorganic fillers in composite materials.
• Pharmaceutical Synthesis: Serves as a protecting group or a synthetic building block in the production of active pharmaceutical ingredients (APIs).
• Release Coating Formulation: A component in formulations for non-stick and release coatings for papers, films, and molds.
• Nanomaterial Functionalization: Used to modify nanoparticles (e.g., silica, quantum dots) for dispersion stability and further chemical grafting.

Quality Control

Our Octyloxydimethylsilyl Chloride is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including assay by GC or titration and impurity profiling, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic and 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 extended stability.
