Description

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Applications
Sodium bis(trimethylsilyl)amide is a strong base used in organic synthesis for deprotonation reactions and base catalyzed reaction. It is also used to enhance the polymerization of pheneylacetylene in conjunction with rhodium(I) catalysis. It is involved in the generation of enolates, Wittig reagents and carbenes.

Solubility
Miscible with benzene and toluene.

Notes
Moisture sensitive. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with oxidizing agents, strong oxidizing agents and oxygen. Dry residue is explosive.
