Sodium methoxide is an organic salt, in pure form a white powder. Sodium methoxide is the conjugate base of methanol. The negatively charged oxygen is more nucleophilic than the neutral oxygen. In biodiesel production, "methoxide" is a product of mixing methanol and sodium hydroxide, yielding a solution of sodium methoxide in methanol, and a significant amount of heat. Sodium Methoxide in methanol is a liquid that kills nerve cells before you can feel the pain.
Typical applications for sodium methoxide are as a solvent, as a methoxide, as condensation agent in organic synthesis, catalyst for treatment of food grease, also as important material of synthesis of pharmaceuticals like sulfadiazine, SMZ, sulfasynergist, etc.
