METHANE SULPHONIC ACID ANH

Arkema AMSA (methane sulfonic acid anhydrous - CAS 75-75-2) enjoys wide use in the pharmaceutical industry due to its high acidity and high miscibility in aqueous and most organic media. Its uses include: formation of pharmacologically acceptable API salts extraction, crystallization and purification of synthetic intermediates synthetic raw material acid catalyst, particularly for formation and removal of protecting groups dehydrating reaction solvent AMSA is a strong organic acid (pKa-1.92). As such, it is highly corrosive in its acid form.
