The preparation of 1 7 0 -and 180-labelled hypophosphate by oxidation of diphosphite (P2-P4 acid) with iodine-water is described. The 162 MHz NMR 31P(18O) isotope shift of 1 8 0 -l a b e l l e d hypophosphate is 2.42 Hz (0.0149 ppm), the relatively large value compared to l\*O-pyrophosphate, 1.73 Hz

## Abstract The ifosfamide metabolite isophosphoramide mustard (IPM) was synthesized with isotopic enrichment at oxygen. Labelled benzaldehyde was made by exchange with isotopically enriched water (13.4 atom % ^17^0, 25.5 atom % ^18^0) and this was then reduced with sodium borohydride to give label
