MOPSO sodium salt (3-(4-Morpholino)-2-hydroxypropanesulphonic acid sodium salt)

MOPSO sodium salt is a zwitterionic aminosulfonate buffer that is very similar in structure to MOPS (3-morpholinopropanesulfonic acid), differing by the presence of a hydroxyl group on C-2 of the propane moiety.


MOPSO has been utilized as a buffer component in the analysis of copper by two distinct methods: (1) a flow injection micellar technique of the catalytic reaction of the reaction between 3-methyl-2-benzothiazolinone hydrazone with N-ethyl-N-(2-hydroxy-3-sulfopropyl)-3,5-dimethoxyaniline; 2 (2) an electrospray-ionization quadrapole time-of-flight mass spectroscopy technique to measure the formation of chelating complexes of MOPSO with copper.
