Identification
Common NameDehydropregnenolone acetate
ClassSmall Molecule
Description16-Dehydropregnenolone acetate (16-DPA) is a chemical compound used as an intermediate or synthon in the production of many semisynthetic steroids. As 7-ACA is for cephalosporins and 6-APA is for penicillins, 16-DPA is for steroids. While it is not easy to synthesize, it is a convenient intermediate which can be made from other more available materials, and which can then be modified to produce the desired target compound.
