Applications

Sodium methoxide is used as a base and a reagent in organic chemistry. It is useful in the synthesis of pharmaceuticals and agrochemicals. It acts as a nucleophile and is used in the production of methyl ethers. It serves as an initiator of anionic addition polymerization with ethylene oxide, forming a polyether with high molecular weight. It is involved in the production of biodiesel from vegetable oils and animal fats.

Notes

Air, moisture and heat sensitive. Incompatible with acids, acid chlorides, acid anhydrides, oxidizing agents, alkali metals, chlorinated solvents, water and reducing agents.
