CAS 865-33-8

Potassium methoxide

Description:

Potassium methoxide, with the CAS number 865-33-8, is an inorganic compound that serves as a strong base and a nucleophile in various chemical reactions. It is the potassium salt of methanol and is typically encountered as a white to off-white solid or as a solution in methanol. This compound is highly soluble in polar solvents, particularly alcohols, and is known for its hygroscopic nature, meaning it can absorb moisture from the air. Potassium methoxide is commonly used in organic synthesis, particularly in the production of esters and in the deprotonation of weak acids. It can also facilitate nucleophilic substitution reactions due to its strong basicity. However, it is important to handle potassium methoxide with care, as it can react vigorously with water and acids, releasing methanol and potentially generating heat. Proper safety precautions, including the use of personal protective equipment, are essential when working with this compound in a laboratory setting.

Potassium methoxide is a strong base that reacts with methanol to produce potassium metal and methanol. It has been used as a model system for studying the reaction mechanism of metal carbonyls. The reaction solution is heated to produce glycol esters, which are catalyzed by the potassium metal. This process can be used to synthesize biologically active molecules, such as anti-inflammatory drugs, which are difficult to make using conventional methods. Potassium methoxide has also been shown to have protective effects against metabolic disorders in mice and has biological properties that may be useful in the treatment of infectious diseases.
