API Intermediate Description: (7a,17b)-7-(9-Bromononyl)-estra-1,3,5(10)-triene-3,17-diol 17-acetate is a synthetic steroid derivative used as a specialized chemical intermediate. It is based on an estrane steroid nucleus bearing phenolic and alcoholic functionalities, with the 17-hydroxyl group protected as an acetate ester. The 9-bromononyl side chain at the 7-position introduces a long, reactive alkyl substituent, where the terminal bromine serves as a handle for further substitution or coupling reactions.
