For procurement managers and R&D professionals in the chemical industry, identifying reliable sources for high-quality intermediates is crucial. Pentafluorophenyltriethoxysilane (CAS 20083-34-5) is one such compound that warrants close attention due to its unique properties and diverse applications. As a leading manufacturer and supplier of specialty organosilicon compounds, we aim to provide B2B buyers with a clear understanding of this versatile chemical.

Pentafluorophenyltriethoxysilane is an organosilicon compound characterized by the presence of a pentafluorophenyl group and three ethoxy groups attached to a silicon atom. Its appearance is typically that of a clear liquid, and it possesses a molecular weight of approximately 330.33 g/mol. Key physical properties include a density around 1.24 g/mL and a boiling point of about 130 °C at 10 mm Hg. Crucially, it exhibits a high degree of hydrolytic sensitivity, meaning its ethoxy groups readily react with moisture to undergo hydrolysis and condensation, forming siloxane linkages. This reactivity is fundamental to its utility in many applications.

The primary uses of Pentafluorophenyltriethoxysilane stem from its unique structure. The electron-withdrawing nature of the pentafluorophenyl group significantly influences the electronic properties of molecules it is incorporated into. This makes it a valuable intermediate in several key areas. Firstly, it is widely used in organic synthesis, particularly in palladium-catalyzed cross-coupling reactions, where it acts as an arylsilane to form new carbon-carbon bonds. This is essential for building complex fluorinated organic molecules. Secondly, its ability to form siloxane networks makes it an excellent candidate for surface modification and the creation of specialized coatings, such as optical coatings, where enhanced thermal stability and chemical resistance are required.

For B2B buyers, understanding these properties is key to evaluating potential suppliers.
