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.

Tetraethyl orthosilicate (TEOS) is an inorganic material used as a precursor for the synthesis of silica-based materials by methods such as sol gel technique, due to its high affinity to water. It can also be used in the synthesis of blended membranes.Will interact with dodecylamine in the formation of intercalation compounds of H+-magadiite and used in a study of mixed-metal bioactive glasses.
