Sodium ethoxide, also known as sodium ethoxide or ethanol sodium, with the CAS number 141-52-6, is an important organic compound primarily used as a strong alkaline catalyst and ethoxylating agent in organic synthesis. It exists as a white to pale yellow, hygroscopic powder that is highly reactive and sensitive to light. Sodium ethoxide readily decomposes upon exposure to air and moisture, releasing sodium hydroxide and ethanol. Due to its strong alkalinity and reactivity, it finds applications in the pharmaceutical and pesticide industries, as well as in the preparation of other organic compounds.
