    • Effective transesterification catalyst
    • Can be customized in solid or liquid form

    Applications

    Sodium Methoxide is widely used in:

    1. Biodiesel Production
      • Acts as a transesterification catalyst to convert vegetable oils or animal fats into methyl esters (biodiesel)
    2. Pharmaceutical Industry
      • Used as a reagent or intermediate in the synthesis of APIs (Active Pharmaceutical Ingredients)
    3. Agrochemicals
      • Involved in the production of herbicides, fungicides, and insecticides
    4. Organic Synthesis
      • Used for deprotonation, condensation, and alkylation reactions
    5. Polymer & Fine Chemicals Manufacturing

    Safety & Handling

    • Reacts violently with water and moisture, releasing methanol and heat
    • Handle under inert gas or dry atmosphere
    • Use proper PPE: gloves, goggles, and protective clothing
    • Refer to the MSDS before handling

    FAQ - Technical & Supply Chain

    • Q:

      Are sodium methoxide and sodium methylate the same substance?

      A: Yes. Sodium methoxide and sodium methylate refer to the same chemical substance and share identical composition under the same CAS identification.
    • Q:

      Is sodium methoxide suitable for biodiesel transesterification processes?

      A: It is commonly used as a base catalyst in biodiesel transesterification where efficient ester conversion is required under controlled industrial conditions.
