Sodium Methyl Mercaptide is a highly reactive organosulfur compound, typically supplied as a 20-25% Aqueous Solution or as a moisture-sensitive solid. It is a powerful nucleophile, essential for the introduction of methylthio groups into various organic molecules during complex synthesis. This chemical is a critical intermediate in the large-scale production of Agrochemicals, specifically for the synthesis of systemic pesticides and herbicides. Its high reactivity ensures efficient conversion rates in industrial reactors, supporting the manufacturing of high-demand crop protection products. The substance is characterized by its strong odor and extreme sensitivity to air and moisture, requiring handling under nitrogen blankets. It provides a specialized sulfur source that is vital for the pharmaceutical industry in the synthesis of methionine and other sulfur-containing active ingredients.

SoleChem, an ISO 9001:2015 certified chemical supplier based in Türkiye, delivers Sodium Methyl Mercaptide (CAS 5188-07-8) to customers in more than 40 countries.
