This invention relates to compounds characterized by the presence of N-methyl, or substituted methyl, phosphonic acid and N-propylenesulfonic acid groups. These compounds contain at least one or more of each group and are bonded to the same or different amino groups. They are derived by reacting an amine with both propane sultone and with a carbonyl compound, such as formaldehyde, and phosphorous acid or its equivalent. They have a wide variety of uses, for example as scale and corrosion inhibitors, chelating agents, etc.
