Sodium ethoxide, 96%, Thermo Scientific Chemicals
Descrizione
Sodium ethoxide is used as a strong base in organic synthesis. It is actively involved in the Claisen condensation, Stobbe reaction and Wolf-kishner reduction. It is an important starting material for the synthesis of ethyl ester and diethyl ester of malonic acid. In Williamson ether synthesis, it reacts with ethyl bromide to form diethyl ether. It is widely used as a base for the generation of carbanions which are utilized for alkylation and condensation reactions.
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.
