Novel amino-hydroxy-alkylene sulfonic acid zwitterions are described which have the general formulas <IMAGE> (FORMULA I) <IMAGE> (FORMULA II) wherein A and B are each independently a hydrogen atom, an aliphatic, cycloaliphatic or hydroxyaliphatic group, n is one or two, and R=N is a cyclic radical comprising one or two ring nitrogen atoms, zero or one ring oxygen atoms and the remainder of the ring being carbon atoms, and water soluble salts of said acids. These organo-sulfonic acid compounds are useful as hydrogen ion buffers in biological research and particularly for tissue culture. |
