Description

Chlorodimethylpentafluorophenylsilane is a high-purity organosilicon reagent featuring a reactive chlorosilane group and a pentafluorophenyl moiety. This compound is a critical building block in advanced materials science and pharmaceutical chemistry, enabling precise surface modification and the synthesis of complex molecules. It is primarily utilized by R&D laboratories and production facilities in the semiconductor, specialty polymer, and life sciences sectors for its unique combination of reactivity and fluorinated aromatic properties.

Application

• Surface Modification Agent: Used to create hydrophobic, oleophobic, or specific functional coatings on glass, silicon wafers, and metal oxides for microelectronics and optics.
• Pharmaceutical Intermediate: Serves as a key synthon in the development of active pharmaceutical ingredients (APIs), particularly where fluorinated aromatic systems are required for bioavailability or metabolic stability.
• Polymer & Resin Synthesis: Acts as a monomer or cross-linking agent in the production of specialty silicones, fluoropolymers, and high-performance resins with enhanced thermal and chemical resistance.
• Catalyst & Ligand Preparation: Employed in the synthesis of novel organometallic catalysts and ligands for asymmetric synthesis and polymerization processes.
• Analytical Chemistry Reagent: Utilized as a derivatization agent in gas chromatography (GC) and mass spectrometry (MS) for the analysis of compounds containing active hydrogens.
• Adhesion Promoter: Functions as a coupling agent to improve adhesion between organic polymers and inorganic substrates in composite materials.

Quality Control

Our Chlorodimethylpentafluorophenylsilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all specification parameters. Our quality commitment supports compliance with relevant standards for research and industrial use.

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). Due to its hygroscopic nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture ingress and hydrolysis. Keep away from strong bases and oxidizing agents.
