Description

5α-Androstan-3-One Ethylene Acetal is a high-purity steroid intermediate, specifically a protected ketone derivative of the 5α-androstane skeleton. This compound is of significant value in pharmaceutical research and development for the synthesis of more complex steroid-based active pharmaceutical ingredients (APIs). It is primarily needed by R&D laboratories, fine chemical manufacturers, and pharmaceutical companies engaged in the production of hormone therapies, anti-inflammatory agents, and other specialized steroid compounds.

Application

• Pharmaceutical Intermediate: A key building block in the multi-step synthesis of therapeutic steroid molecules, including corticosteroids and androgens.
• Research & Development: Used in medicinal chemistry for structure-activity relationship (SAR) studies and the development of novel steroid-based drug candidates.
• Fine Chemical Synthesis: Serves as a versatile precursor for creating custom steroid derivatives with modified biological activity.
• Reference Standard: Employed as an analytical standard in quality control laboratories for method development and impurity profiling.
• Biochemical Research: Utilized in studies investigating steroid hormone metabolism and receptor interactions.
