Description

3-[1,3,3,3-Tetramethyl-1-[(Trimethylsilyl)Oxy]Disiloxanyl]Propyl Hydrogen Sulphate is a specialized organosilicon sulfonate compound that serves as a key reactive intermediate in advanced material synthesis. Its unique bifunctional structure, featuring both a hydrolytically stable siloxane group and a reactive sulfate ester, makes it invaluable for introducing permanent anionic charges or sulfonate functionalities onto surfaces and polymer backbones. This product is essential for R&D and production teams in the specialty chemicals, advanced materials, and surface treatment industries seeking to modify material properties such as hydrophilicity, adhesion, and conductivity.

Application

• Surface Modification Agent: Used to create hydrophilic, anionic, or anti-fog coatings on glass, plastics, and optical lenses.
• Polymer Functionalization: Acts as a reactive monomer or grafting agent to introduce sulfonate groups into silicones and other polymers, enhancing ionic conductivity or water compatibility.
• Adhesion Promoter: Improves the bonding between inorganic substrates (like glass or metals) and organic polymers or coatings.
• Specialty Surfactant Intermediate: Employed in the synthesis of novel silicone-based surfactants and emulsifiers for demanding formulations.
• Release Coating Chemistry: Serves as a key component in the synthesis of controlled-release coatings for industrial and medical applications.
• Electrolyte Additive: Investigated for use in advanced battery systems to modify electrode-electrolyte interfaces.

Quality Control

Our production of 3-[1,3,3,3-Tetramethyl-1-[(Trimethylsilyl)Oxy]Disiloxanyl]Propyl Hydrogen Sulphate adheres to stringent quality management protocols to ensure batch-to-batch consistency and purity. Each lot undergoes comprehensive analysis, including assay by titration or NMR, identity confirmation via FT-IR, and quantification of key impurities. A Certificate of Analysis (COA) detailing all relevant specifications is 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 temperatures between 15-25°C. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and degradation. Keep away from strong bases and oxidizing agents.
