Description

MilliporeSigma Sigma Organics products encompass a wide range of quality reagents, solvents, catalysts, and building blocks for organic synthesis. From benchtop discovery to process development and scale-up, Sigma Organics solutions are built to meet the needs of synthetic chemists.

Triethoxy(octyl)silane (TEOS) is an alkoxide organosilane with four ethyl ester sidechains. It is used as a self-assembled monolayer and provides a hydrophobic coating with low surface energy. The water contact angle is in the range of 150-170.Triethoxy(octyl)silane may be used to prepare several formulations for fabricating low-cost, colorimetric sensor arrays to detect toxic gases.
