## Abstract After successfully synthesizing 16__α__‐[^18^F]fluoroestradiol‐3,17__β__‐disulphamate in an automatic procedure, we studied the conditions for obtaining 16__α__‐[^18^F]fluoroestradiol‐monosulphamates in a similar manner. The described procedure can simultaneously provide approximately 3
16α‐[^18^F]Fluoroestradiol (16α‐[^18^F]FES, 1) is known as a valuable tracer in molecular imaging as estrogen receptor (ER) ligand for investigation of primary and metastatic breast cancer. ER concentration in human breast tumor cells is a significant indicator for the degree of disease and is often
Although the reported synthesis of the title compound resulted in a high radiochemical yield (43% based on resolubilized 18F), the effective specific activity at EOS was low (166 Ci/mmol). Reduction in the amount of carrier fluoride in the target water improved the effective specific activity of the
