An improved labeling procedure for 15-(p-[123I]iodophenyl)pentadecanoic acid (IPPA) is reported. The exchange labeling yield was greater than 95%. The radiochemical yield is influenced by the presence of sodium. The major advantage of this method is that very high specific activity i.e. upto 190 mCi

The uptake and turnover of omega(p 123I iodophenyl-)pentadecanoic acid (I-PPA), a radioiodinated free-fatty-acid analog, was examined in the heart, lung, liver, kidneys, spleen, and skeletal muscle of rats. At 2 min post injection, a high cardiac uptake of 4.4% dose per gram had already been achieve
15-(p-Iodophenyl) pentadecanoic acid labelled with carbon-14 in the carboxyl group is obtained with good yields in five steps from [14C]NaCN, starting from 14-bromo 1-phenyl tetradecane 2. Specific radioactivity: 0.019 mCi/mg, 8.45 mCi/mmol; radiochemical yield: 74.6%.
