Description

Dichloromethyl(3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl)silane (CAS No. 73609-36-6) is a high-purity organosilicon compound with the molecular formula C₉H₇Cl₂F₁₃Si. This specialty chemical is widely used in surface modification, hydrophobic coatings, and as a precursor for fluorinated silane coupling agents. Its unique structure combines a reactive dichloromethylsilane group with a highly fluorinated carbon chain, making it ideal for applications requiring both chemical reactivity and extreme hydrophobicity/oleophobicity.

Our product is manufactured under strict quality control measures to ensure consistency and purity (>98%), making it suitable for research and industrial applications. The compound is particularly valuable in materials science for creating low-surface-energy coatings, modifying nanoparticles, and functionalizing surfaces in microfluidic devices. It should be handled with care under inert atmosphere due to its moisture sensitivity.

Available in various packaging options from research quantities to bulk orders, this product ships with comprehensive technical documentation including NMR spectra, HPLC purity data, and detailed safety information.
