Used primarily as an intermediate in the synthesis of corticosteroid pharmaceuticals. Its structure allows for further chemical modifications to produce active ingredients in anti-inflammatory and immunosuppressive drugs. Commonly employed in the preparation of steroid derivatives with enhanced biological activity and stability. Due to the presence of reactive functional groups, it facilitates selective transformations in multi-step steroid synthesis. Widely utilized in research and development of hormonal therapies and in the manufacturing of high-purity steroid APIs.
