Bisphosphonate compounds are of the Formula (I): ##STR1## wherein Y is .dbd.O or .dbd.N--OH and n is from 3 to 24, and further wherein when Y is .dbd.O, (i) R.sub.1 is hydrogen and R.sub.2 is sodium, or (ii) R.sub.1 is sodium and R.sub.2 is methyl, and when Y is .dbd.N--OH, R.sub.1 is sodium and R.sub.2 is methyl.
双膦酸化合物的化学式为(I):##STR1## 其中Y为.dbd.O或.dbd.N--OH,n为3至24,且进一步当Y为.dbd.O时,(i) R.sub.1为氢且R.sub.2为钠,或(ii) R.sub.1为钠且R.sub.2为甲基,当Y为.dbd.N--OH时,R.sub.1为钠且R.sub.2为甲基。
