Description

1H,1H,2H,2H-Perfluorooctanethiol is a high-value fluorinated thiol compound, essential for creating ultra-low surface energy coatings and self-assembled monolayers (SAMs). Its unique structure, featuring a perfluorinated carbon chain terminated with a thiol group, provides exceptional hydrophobicity, oleophobicity, and chemical resistance. This makes it a critical material for advanced surface modification in the electronics, optics, and specialty materials industries.

Application

• Surface Modification Agent: Used to create hydrophobic and oleophobic coatings on metals, glass, and semiconductors for anti-fouling, anti-corrosion, and easy-clean surfaces.
• Self-Assembled Monolayers (SAMs): A key precursor for forming highly ordered molecular films on gold, silver, and other substrates for biosensor development and nanotechnology research.
• Electronics & Microfabrication: Applied in the surface treatment of microelectromechanical systems (MEMS), nanoimprint lithography, and as a release agent.
• Specialty Polymer Additive: Imparts oil and water repellency, as well as chemical stability, when incorporated into fluoropolymers and high-performance resins.
• Textile & Leather Finishing: Provides durable water and stain repellency to high-end technical fabrics and leather goods.
• Research & Development: Serves as a building block in organic synthesis for developing novel fluorinated materials and pharmaceuticals.

Quality Control

Our 1H,1H,2H,2H-Perfluorooctanethiol is manufactured under strict quality protocols. Each batch undergoes rigorous analytical testing, including GC, NMR, and FTIR, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and R&D processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C) under an inert atmosphere (e.g., nitrogen or argon) due to its sensitivity to oxidation and high volatility. Keep away from heat, sparks, and open flame.
