Description

Trimethoxy(Pentafluorophenyl)Silane is a highly reactive organosilicon compound featuring a pentafluorophenyl group, making it a valuable building block for advanced material synthesis. Its core value lies in its ability to introduce both silicon and fluorine functionalities onto surfaces and into polymers, imparting unique properties like hydrophobicity, chemical resistance, and low surface energy. This specialty silane is essential for researchers and manufacturers in the semiconductor, coatings, and specialty polymer industries seeking to engineer materials with enhanced performance characteristics.

Application

• Surface Modification Agent: Used to functionalize silica, glass, and metal oxide surfaces to create hydrophobic, oleophobic, or chemically resistant coatings.
• Adhesion Promoter: Enhances the bonding between inorganic substrates (like glass or metals) and organic polymers (epoxies, silicones) in composite materials and sealants.
• Monomer for Fluorinated Polymers: Serves as a key precursor in the synthesis of fluorinated polysilsesquioxanes and other hybrid organic-inorganic materials with low dielectric constants and high thermal stability.
• Semiconductor Industry: Employed in the fabrication of low-k dielectric films and as a surface passivation agent in microelectronics.
• Chromatography Stationary Phases: Used to derivatize silica gel to create specialized phases for HPLC with unique selectivity, particularly for fluorinated analytes.
• Catalyst and Ligand Synthesis: Acts as a precursor for creating sophisticated ligands in organometallic chemistry and catalysis.

Quality Control

Our Trimethoxy(Pentafluorophenyl)Silane is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including GC, NMR, and Karl Fischer titration. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and R&D requirements.

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 hydrolysis and maintain product integrity.
