The preparation of 9α, 11ζ‐tritiated estrone‐3‐methyl ether with high specific activity is described. The following syntheses gave 17α‐CH 2 X‐derivatives of estradiol (X = CN and SCN) with high specific activity and radiochemical purity higher than 98%. Radiolysis and storage conditions are examined.
