Technetium-99m-d,1-hexamethylpropyleneamine oxime (/sup 99m/Tc)d,1-HM-PAO) is a neutral-lipophilic chelate formed from a kit in high yield by stannous reduction of Na/sup 99m/TcO/sup 4 -/. Of three methods used to analyze the purity of the /sup 99m/Tc complexes, a single strip method using ether as the developing solvent was the most rapid and simple to perform. The lipophilic chelate converts to /sup 99m/TcO/sup 4 -/ and other hydrophilic products with time and this limits the useful lifetime of the preparations. The rate of decomposition of (/sup 99m/Tc)d,1-HM-PAO increased in the presence of excess stannous ion and at pH greater than 9.
