A radiobrominated compound, 4,5,6,7‐tetrachloro‐2′,4′,5′,7′‐tetrabromofluorescein‐ 77 Br 4 was prepared from resorcinol, tetrachlorophthallic anhydride and Na 77 Br by a two‐step synthesis. The precursor was identified by spectrometry. Final purification utilized column chromatography. The product was identified by thin layer chromatography and spectrometry. The yield was 60% of theoretical.
