Sodium methylate solution is widely used as a catalyst in the production of biodiesel. It facilitates the transesterification process, where vegetable oils or animal fats are converted into fatty acid methyl esters (FAME), the primary component of biodiesel. This chemical is preferred due to its high efficiency and ability to accelerate the reaction at relatively low temperatures.

In the pharmaceutical industry, it serves as a strong base in various organic synthesis reactions, including the production of active pharmaceutical ingredients (APIs). It is also employed in the manufacture of vitamins and other fine chemicals.

Additionally, sodium methylate solution is utilized in the production of synthetic resins and plastics, where it acts as a polymerization initiator or cross-linking agent. Its role in these processes helps improve the durability and performance of the final products.

In the agricultural sector, it is used in the synthesis of pesticides and herbicides, contributing to the development of effective crop protection solutions. Its versatility and reactivity make it a valuable chemical across multiple industries.
