Description

Diethoxybis(4-Perfluorotolyl)Silane is a highly fluorinated organosilicon compound characterized by its unique perfluorinated aromatic substituents. This specialty silane is engineered to provide exceptional hydrophobicity, oleophobicity, and chemical resistance, making it a critical intermediate for advanced material synthesis. It is primarily sought after by R&D and production teams in the pharmaceutical, agrochemical, and high-performance polymer industries for developing novel fluorinated coatings, surface modifiers, and specialty monomers.

Application

• Fluorinated Polymer Synthesis: A key monomer for creating high-performance fluorosilicones and fluorinated polyimides with enhanced thermal stability and chemical resistance.
• Surface Modification Agent: Used to impart permanent water- and oil-repellent (omniphobic) characteristics to glass, ceramics, and metal surfaces.
• Pharmaceutical Intermediate: Serves as a building block in the synthesis of fluorinated active pharmaceutical ingredients (APIs) and diagnostic agents.
• Agrochemical Formulations: Employed in the development of advanced, weather-resistant pesticide and herbicide delivery systems.
• Specialty Coatings & Resins: Incorporated into formulations for anti-graffiti, anti-fouling, and low-surface-energy industrial coatings.
• Electronic Materials: Used in the fabrication of low-k dielectric materials and as a surface treatment for microelectronic components.

Quality Control

Every batch of Diethoxybis(4-Perfluorotolyl)Silane is manufactured and tested under strict quality management protocols to ensure consistency and reliability for your critical applications. We provide comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles, typically verified by GC, HPLC, NMR, and FTIR analysis. Our quality system is designed to support cGMP and ISO standards for traceability and documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under a dry inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and maintain purity. Keep away from strong bases and incompatible organic solvents.
