16-Dehydropregnenolone acetate (16-DPA) is a chemical compound used as an intermediate or synthon in the production of many semisynthetic 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.
