Abstract
Novel dimeric and monomeric selenium-75 derivatives of steroids are made by reacting a keto steroid with selenium-75 dioxide or selenious acid-Se75. The resulting diselenide dimers can be converted into monomeric compounds by the use of a cleaving reagent followed by an alkylating agent. The compounds are useful in saturation analyses such as radioimmunoassays.
