title: High specific activity 15-(p-[123I]iodophenyl)pentadecanoic acid.
abstract: 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/mg labeled IPPA can be prepared.
