  • Applications

    Dehydroepiandrosterone (DHEA), CAS 53-43-0, is primarily used as a chemical intermediate in the synthesis of steroid hormones and related pharmacologically active steroids for pharmaceutical manufacturing. It also serves as a biochemical reagent and reference material in research on steroid metabolism and enzymology. In some markets it is used as a cosmetic ingredient or precursor in personal care formulations. Additionally, it is treated as a regulated intermediate and building block for API development in pharmaceutical programs, with usage governed by local regulations.
