Octadecylsilane

Description:

Octadecylsilane, with the CAS number 18623-11-5, is an organosilicon compound characterized by its long hydrophobic alkyl chain, which consists of 18 carbon atoms. This structure imparts significant hydrophobic properties, making it useful as a surface modifier and coupling agent in various applications. Octadecylsilane is typically a colorless to pale yellow liquid or solid, depending on its form and purity. It is soluble in organic solvents but insoluble in water, which enhances its utility in creating hydrophobic surfaces on materials such as glass, metals, and polymers. The compound can form self-assembled monolayers (SAMs) on surfaces, providing a barrier against moisture and enhancing chemical resistance. Additionally, it is often used in the preparation of functionalized silica and as a reagent in organic synthesis. Safety considerations include handling it in a well-ventilated area and using appropriate personal protective equipment, as it may pose health risks if inhaled or ingested. Overall, octadecylsilane is valued for its ability to modify surface properties and improve material performance in various industrial applications.
