Departments of Chemistry and of Physiology and Biophysics, University of Illinois, Urbana, Illinois 61801 Received September 4, 1990; Revised Manuscript Received November 21, 1990 abstract: 3-(4-Azido-2, 3, 5, 6-tetrafluorobenzoyl)-6-hydroxy-2-(4-hydroxyphenyl) benzo [6] thiophene 1 (tetrafluoroaryl azide, TFAA) and itsprotio analogue 3-(4-azidobenzoyl)-6-hydroxy-2-(4-hydroxy-phenyl) benzo [6] thiophene 2 (protioaryl azide, PAA), photoaffinity labeling (PAL) reagents for the estrogen receptor (ER), have been prepared inhigh specific activity tritium-labeled form (19 Ci/mmol) and shown to undergo selective and efficient photocovalent attachment to ER from rat uterus. Both azides 1 and 2 demonstrate high binding affinity for ER as determined by both a competitive binding assay (relative binding affinities: estradiol= 100; TFAA=
