Potassium ethoxide

Description:

Potassium ethoxide, with the chemical formula C2H5OK, is an alkoxide derived from potassium and ethanol. It appears as a white to off-white solid and is highly soluble in polar solvents such as ethanol and other alcohols, while being less soluble in non-polar solvents. This compound is hygroscopic, meaning it readily absorbs moisture from the air, which can lead to hydrolysis and the formation of potassium hydroxide and ethanol. Potassium ethoxide is a strong base and is often used as a reagent in organic synthesis, particularly in deprotonation reactions and as a catalyst in various chemical processes. It can also serve as a nucleophile in substitution reactions. Due to its reactivity, it should be handled with care, as it can react violently with water and acids, releasing flammable hydrogen gas. Proper storage in a dry, inert atmosphere is essential to maintain its stability and prevent degradation.

Potassium ethoxide

CAS: 917-58-8

Potassium ethoxide is an ethoxide of potassium. Potassium ethoxides are used as reactive chemicals in the treatment of wastewater, with applications such as neutralization. Potassium ethoxides can also be used to synthesize x-ray crystal structures and has shown potent antitumor activity in mice. The mechanism of action is not known, but it is thought that potassium ethoxides react with activated oxygen species and form superoxide radicals. This reaction may lead to cell death by inhibiting DNA synthesis or by damaging cellular membranes.
