Description

17,21-Dihydroxypregn-4-Ene-3,11,20-Trione 21-Heptanoate is a synthetic steroid derivative, specifically a heptanoate ester of a pregnane-based triketone. This compound is a critical pharmaceutical intermediate used in the synthesis of more complex steroid-based active pharmaceutical ingredients (APIs). It is primarily required by research institutions and pharmaceutical manufacturers engaged in the development and production of corticosteroid drugs.

Application

• Key Intermediate in Corticosteroid Synthesis: Serves as a crucial building block in the multi-step synthesis of potent glucocorticoids and other therapeutic steroids.
• Pharmaceutical Research & Development (R&D): Used in medicinal chemistry for the discovery and structural modification of new steroid-based drug candidates.
• Process Chemistry & Scale-Up: Employed in the development and optimization of commercial-scale manufacturing processes for steroid APIs.
• Reference Standard: Utilized as an analytical standard in quality control laboratories for method development and impurity profiling of related steroid products.
• Biochemical Research: Applied in studies investigating steroid hormone metabolism, receptor interactions, and enzymatic pathways.
