Bidentate monophosphates--phosphonoacetate (PAA), 2-phosphonoproprionate (PPA), 2-methyl-2-phosphonoproprionate (MPPA), and carbamyl phosphate (CAP)--which are pyrophosphate analogs, were successfully labeled with Sn(II)-reduced [99mTc] pertechnetate in high yield (greater than 95%). Biodistribution studies show that these Tc-99m-labeled monophosphates do localize in bone. At 2
