Organo Phosphonates

                                             

• Phosphonates are anthropogenic complexing agents containing one or more C–PO(OH)2 groups.
• Phosphonates are molecules with a characteristic C–PO3H2 group.
• They are used in numerous technical and industrial applications as chelating agents and scale inhibitors.
• Phosphonates are similar to phosphates except that they have a carbon–phosphorous (C–P) bonding place of the carbon–oxygen phosphorous (C–O–P) linkage.
