Used in the synthesis of dexamethasone derivatives, this compound serves as a key intermediate in pharmaceutical manufacturing. Its aldehyde functional groups at positions 17, 20, and 21 allow for selective chemical modifications, enabling the production of steroid analogs with enhanced anti-inflammatory, immunosuppressive, or metabolic properties. It is particularly valuable in developing customized glucocorticoids for targeted therapies in dermatology, rheumatology, and oncology. Due to its reactivity, it supports the creation of prodrugs and conjugated forms that improve drug delivery, stability, and tissue specificity.
