Description

11-Ketodehydroepiandrosterone is a significant ketosteroid derivative of dehydroepiandrosterone (DHEA). This compound serves as a key synthetic intermediate and reference standard in the research and development of steroid-based pharmaceuticals and biochemical studies. It is primarily utilized by pharmaceutical R&D laboratories, contract research organizations (CROs), and fine chemical manufacturers engaged in steroid chemistry, metabolic pathway analysis, and the production of specialized active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of more complex steroid hormones and therapeutic agents.
• Biochemical Research: Used as a reference standard or analytical reagent in studies of steroid metabolism, enzyme activity (e.g., 11β-hydroxysteroid dehydrogenase), and endocrine pathways.
• Reference Material: Serves as a high-purity certified reference material (CRM) for quality control and method validation in analytical laboratories.
• Academic & Institutional Research: Employed in universities and research institutes for investigating the biological role of 11-oxygenated androgens.
• Fine Chemical Synthesis: Utilized as a building block for creating novel steroid derivatives with potential biological activity.
