Potassium methoxide is a strong base and alkylating agent, widely used in organic synthesis for transesterification, methylation reactions, and as a catalyst in polymer production. It appears as a hygroscopic white solid or solution, highly reactive with moisture and acids. With a CAS number of 865-33-8, molecular formula CH3OK, and molecular weight of 70.13, it requires careful handling under ambient storage conditions. The product carries a **Danger** signal word due to its corrosive and flammable properties. Molekula supplies potassium methoxide from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
