Webluminescent acridine ester precursors with the toxic carcinogen 1,3-propane sultone. In the current study, we report that sodium 3-bromopropane sulfonate in ionic liquids (ILs) is a benign alternative to 1,3-propane sultone for introducing the N-sulfopropyl group in chemiluminescent acridinium ester labels. The sultone reagent can be WebThis class of polyelectrolytes is only five decades old, since the first synthesis was in 1952. Polycarboxybetaines, polysulfobetaines, polyphosphobetaines and a few more. Recent progress in the field of zwitterionic polyelectrolytes is reviewed. This class of polyelectrolytes is only five decades old, since the first synthesis was in 1952.
