China and Germany are the leading exporters of methanesulfonic acid, accounting for a substantial share of global supply, while the United States, South Korea, and Japan represent the largest importers. Methanesulfonic acid prices have remained relatively stable amid steady cross-border flows, reflecting consistent industrial demand in electroplating and pharmaceutical synthesis. Export volumes from China have increased modestly over the past two years, while imports into the U.S. and South Korea have shown resilience despite broader chemical trade fluctuations.
Methanesulfonic acid (MSA) is a colorless to pale yellow, hygroscopic liquid with a pungent odor and low volatility; it has a melting point of ~20 °C and a boiling point of ~167 °C at 100 mmHg. It is a strong organic sulfonic acid and classified as a specialty organic chemical and process acid. MSA is widely used as a catalyst and acidifying agent in fine chemical synthesis, particularly in pharmaceutical and agrochemical manufacturing, where its high acidity, thermal stability, and biodegradability offer advantages over mineral acids. It serves as a key intermediate in the production of methanesulfonates (e.g., methyl methanesulfonate), metal plating electrolytes (especially for tin and lead–tin alloys), and specialty esters for coatings and electronic materials.
Methanesulfonic acid is a raw material for medicine and pesticide. It can also be used as dehydrating agent, curing accelerator for coating, treating agent for fiber, solvent, catalysis, and esterification as well as polymerization reaction.It can be used as solvent, alkylation, catalyst of esterification and polymerization, also used in medicine and electroplating industry. It can also be applied to oxidation.
