Octadecyltrimethoxysilane

Product name:Octadecyltrimethoxysilane

CAS:3069-42-9

Molecular Formula:C21H46O3Si

Molecular Weight: 374.67g/mol

Description:This product occurs as colorless transparent liquid with its melting point 16-17 °C(lit.) and boiling point 170 °C (0.1 mmHg).It is stable but incompatible with strong oxidizing agents. Octadecyltrimethoxysilane is an oraganosilane often used for its ability to create a self-assembled monolayer. It commonly goes by the name OTMS and is hygroscopic. The formation of OTMS monolayers is used for generating homeotropic anchoring of a liquid crystal at a surface. OTMS forms a self-assembling monolayer by binding with hydroxyl groups at the surface of the material. Subsequent dipole-dipole interactions between mesogens and the OTMS molecules induce the homeotropic anchoring condition.Its purity is not less than 85.0%(GC).The specification is 25ML.
