Potassium Methoxide (CAS 865-33-8) Manufacturer, Supplier & Exporter in China

Potassium Methoxide Product Introduction

Potassium methoxide, also known as potassium methylate, is a strong-base alkali metal alcoholate widely used in organic synthesis and biodiesel production. Its chemical name is potassium methoxide (methanol, potassium salt), CAS number 865-33-8, molecular formula CH3KO, molecular weight 70.13. As an efficient transesterification catalyst, potassium methoxide is a key raw material for biodiesel manufacturing, pharmaceutical intermediates and fine chemical synthesis. As a professional potassium methoxide manufacturer in China, we supply potassium methoxide (CAS 865-33-8) in both solid and 32% methanol solution forms, with stable quality, competitive prices and reliable export service.
