Abstract
Monoradioiodinated derivatives of compounds employed in a radioassay prepared from precursors which are either active esters, amino acids, or amines, including a phenolic of imidazole substituent group in which one of the possible two sites on the group for radioiodination is substituted to permit production of a monoradioiodinated derivative. A preferred precursor is an active ester of 3-fluoro-5-radioiodotyrosine which can be coupled to a compound including an amino group to produce a monoradioiodinated derivative of the compound.
