Sodium ethoxide, 21% w/w in ethanol is used as a strong base in organic synthesis. It finds application in various chemical reactions such as condensation, esterification, alkoxylation and etherifcation. It is actively involved in 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.
