sodium methoxide solution is a dangerous caustic base used in organic synthesis. It reacts violently with water and air but is soluble in alcohols such as methanol. It is a white hygroscopic powder that is not readily available, but it can be prepared by slowly and carefully adding metallic sodium to an excess of anhydrous methanol.

The resulting solution can be stored in an inert atmosphere. It has a density of 0.945 g/mL at a temperature of 25 degC. The lower explosion limit of this compound is 73% (V) and the upper explosion limit is 36% (V). It is a strong reducing agent. Sodium methoxide is also known as CH3ONa and has the CAS reference number of 124-41-4.

Upon reaction with water, the substance forms methanol and sodium hydroxide, which are both toxic. Sodium methoxide is highly corrosive to the eyes, skin and respiratory tract. It is also toxic to aquatic organisms.

Sodium methoxide is a poisonous chemical and must be kept in an inert atmosphere. It should not be exposed to heat, flame or steam. It is flammable, and it reacts violently with acids and chlorinated solvents. It is also toxic to the environment and should not be disposed of in water sources or sewers. It is a Schedule I compound in the US. It is regulated by the Environmental Protection Agency and must be kept away from fuels and other combustibles. It is a very dangerous material that must be handled by trained personnel.
