Product overview

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.
