MES buffers are Morpholine Ethane Sulphonic Acid or CAS 4432-31 buffers with compound 2-(N-morpholino)ethane sulfonic acid. Its chemical structure contains a morpholine ring. It has a molecular weight of 195.2 g/mol and the chemical formula is C6H13NO4S. Synonyms include 2-morpholinoethanesulfonic acid; 2-(4-morpholino)ethane sulfonic acid; 2-(N-morpholino)ethane sulfonic acid; 2-(4-morpholino)ethane sulfonic acid; MES; MES hydrate; and morpholine-4-ethanesulfonic acid hydrate. MOPS is a similar pH buffering compound which contains a propane sulfonic moiety instead of an ethane sulfonic one.
