Description and Uses

Sodium methoxide is mainly used as a condensation agent, a strong alkaline catalyst and a methoxylating agent for the production of vitamin B1 and A, sulfadiazine and other drugs, and in small quantities for the production of pesticides. It is also used as a catalyst for treatment ofedible fats and oils, as an intermediate inmany synthetic reactions, to prepare sodiumcellulosate; and as a reagent in chemicalanalysis.
