Vitamin a derivatives labelled with 131I — Potential agents for liver scintigraphy

Two retinol derivatives, 4-[(131I)-4-iodobenzoyloxy]retinol propionate and 4-[(131I)-3-iodobenzylcarbamoyl] retinol propionate, were synthesized and their biodistribution in rats was studied in vivo by the whole body scintigraphy.
