Estrone is one of the naturally occurring estrogens, an estrogenic hormone which is secreted by the ovary and adipose tissue. It is synthesized from 4-androstenedione and is carcinigenic for human females. Reference standards of Estrone API, and its pharmacopeial, non pharmacopeial impurities, and stable isotopes are listed below.
