Potassium Methoxide(KM)

Potassium Methoxide (KM, CH₃OK) is a white powder that readily absorbs moisture, decomposes upon contact with water, and dissolves in organic solvents such as methanol. It is produced by reacting methanol with metallic potassium or potassium hydroxide. It serves as a catalyst in organic synthesis, an additive in biodiesel production, and is also used in the synthesis of pharmaceutical intermediates. Store in a sealed container to prevent moisture absorption, keep away from water and acids, and ensure proper protective measures during handling.
