Product Details

Sodium Methoxide  #CAS124-41-4

Sodium Methoxide (CAS No. 124-41-4) is a strong organic base and an important catalyst widely used in the pharmaceutical, agrochemical, biodiesel, and fine chemical industries. It is commonly employed in transesterification, condensation, and alkoxylation reactions. Due to its high reactivity and strong basicity, sodium methoxide is one of the most important catalysts in organic synthesis.

Due to its highly reactive nature, Sodium Methoxide should be handled with appropriate safety precautions. Direct contact with moisture, water, acids, and oxidizing agents should be avoided. Proper personal protective equipment should be worn during handling, and storage areas should be cool, dry, and well ventilated.

With its outstanding catalytic activity, versatility, and broad range of industrial applications, Sodium Methoxide remains one of the most valuable chemical reagents for modern chemical manufacturing and sustainable energy

In the pharmaceutical industry, Sodium Methoxide is extensively utilized in the synthesis of active pharmaceutical ingredients (APIs), vitamins, antibiotics, and other pharmaceutical intermediates. In the agrochemical sector, it serves as an essential reagent in the manufacture of herbicides, insecticides, fungicides, and specialty crop protection chemicals. Additionally, it is widely employed in the production of fragrances, dyes, pigments, surfactants, and other fine chemical products.

Application of Sodium Methoxide 

Sodium Methoxide is a highly reactive strong base and one of the most important industrial catalysts in modern chemical manufacturing. Due to its excellent catalytic performance and strong alkalinity, it is widely used across multiple industries, particularly in large-scale organic synthesis and energy-related chemical processes.

One of the largest application areas of Sodium Methoxide is biodiesel production. It is used as a catalyst in the transesterification reaction between vegetable oils (or animal fats) and methanol, producing fatty acid methyl esters (FAME), which are the main components of biodiesel.

Sodium Methoxide is widely used in pharmaceutical synthesis as a strong base and reaction catalyst. It plays an important role in the production of active pharmaceutical ingredients (APIs) and key intermediates.

Typical applications include alkylation, condensation, and rearrangement reactions. It is also used in the synthesis of vitamins, antibiotics, and various high-value pharmaceutical compounds.
