Description

1H,1H,2H,2H-Perfluorodecyltrichlorosilane (CAS: 78560-44-8) is a highly specialized fluorinated silane compound with the molecular formula C₁₀H₄Cl₃F₁₇Si. This organosilane is widely recognized for its exceptional hydrophobic and oleophobic properties, making it an indispensable reagent for surface modification and functionalization in advanced material science applications. The compound features a perfluorinated alkyl chain (C10) coupled with a trichlorosilane group, enabling covalent bonding to hydroxylated surfaces such as glass, silicon, and metal oxides.

With a purity of 96%, this product is rigorously tested to ensure consistency and performance in demanding research and industrial environments. It is commonly stabilized over copper powder to enhance shelf life and handling safety. Applications span nanotechnology, microelectronics, biomedical coatings, and self-assembled monolayers (SAMs), where ultra-low surface energy and chemical resistance are critical.

Synonyms include FDTS, HFTCS, Trichloro(1H,1H,2H,2H-perfluorodecyl)silane, and others (see full list). Available in research quantities with detailed technical data sheets (TDS) and safety documentation (SDS). Store under inert conditions to prevent hydrolysis.

This fluorinated silane is primarily used to create ultra-hydrophobic and chemically resistant coatings on substrates like silicon wafers, glass slides, and nanoparticles. It forms self-assembled monolayers (SAMs) that repel water, oils, and organic contaminants, ideal for microfluidic devices and anti-fouling surfaces. In electronics, it serves as a dielectric layer or adhesion promoter. Biomedical researchers employ it to reduce non-specific binding in biosensors. Always handle under nitrogen/argon due to moisture sensitivity.
