N-OCTADECYLDIMETHYLMETHOXYSILANE Chemical Properties,Usage,Production

Uses

Silica spheres for HPLC colums were reported to be functionalized with methoxy(dimethyl) octadecylsilane. 1 Methoxy(dimethyl) octadecylsilane may be grafted on the surface of ZnO nanoparticles. 2

General Description

Methoxy(dimethyl)octadecylsilane(MDOS) is an organosilane with one methoxy group. It is a silane coupling agent which forms a self-assembled monolayer(SAM) on a variety of particles.
