Description

1H,1H,2H,2H-Perfluoroalkyl-1-Thiols CAS NO 68140-20-5 are a specialized class of fluorinated thiols characterized by a perfluoroalkyl chain attached to a thiol (-SH) group via a short hydrocarbon spacer. These compounds are critical for introducing low surface energy and exceptional chemical resistance into materials and surfaces. They are essential for manufacturers in the coatings, electronics, and specialty materials sectors seeking to enhance performance characteristics like hydrophobicity, oleophobicity, and release properties.

Application

• As a key surface modifier and coupling agent in anti-fingerprint, oleophobic, and hydrophobic coatings for touchscreens, optical lenses, and protective films.
• For the functionalization of nanoparticles and surfaces to create self-assembled monolayers (SAMs) with tailored interfacial properties.
• As a building block or intermediate in the synthesis of advanced fluorinated polymers and surfactants for demanding industrial applications.
• In the formulation of release agents and mold treatment products for the plastics and rubber manufacturing industries.
• For modifying the surface of textiles and nonwovens to impart durable water and oil repellency (DWR).
• As a chemical anchor to attach functional molecules to gold and other metal surfaces in sensor and electronic device fabrication.

Quality Control

Our 1H,1H,2H,2H-Perfluoroalkyl-1-Thiols are produced under stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent purity, composition, and performance. Comprehensive Certificates of Analysis (COA) detailing key parameters such as assay, identity, and impurity profiles are provided to guarantee they meet your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Due to its easily oxidized nature, minimize exposure to air during handling and use. Recommended storage temperature is 2-8°C for long-term stability.
