Methanesulfonic Acid (MSA) is a powerful, non-oxidizing organic acid provided as a 70% solution or anhydrous form. It is recognized as a "green" acid due to its biodegradability and lower environmental impact.
Compared to traditional mineral acids, MSA offers high thermal stability and superior solubility for metal salts. It is a highly efficient catalyst in esterification and alkylation reactions in chemical processing.
This Technical Grade acid is non-fuming and easy to handle in industrial settings, reducing equipment corrosion. Its high ionic conductivity makes it a premier choice for electroplating and modern battery applications.
SoleChem, an ISO 9001:2015 certified chemical supplier based in Türkiye, delivers Methanesulfonic Acid (CAS 75-75-2) to customers in more than 40 countries.
