description	In one embodiment, a scale inhibitor comprising at least one polymethylenephosphonate derivative having the following formula: wherein n is a number, wherein M is hydrogen or a cation, wherein R1, R2, and R3 are each independently selected from the group consisting of CH2PO3M2, CH2R4, wherein R4 is CHOHCH3, CHOHCH2Cl, or CHOHCH2OH, (CH2)mSO3M, wherein m is 3 or 4, and CH2CH2R5, wherein R5 is CONH2, CHO, COOR6, COOX, or CN, wherein R6 is CH3 or C2H5, and wherein X is an alkali metal or ammonium, and wherein at least one of R1, R2, and R3 is not CH2PO3M2. In another embodiment, a method for inhibiting scale formation in water, and in still another embodiment, a method for sequestering iron ions in a water systems, each of the methods comprising the step of providing the water with the above described polymethylenephosphonate derivative.
