Description

17Beta-Hydroxyestr-4-En-3-One 17-(3-Cyclohexylpropionate) is a synthetic steroid ester, specifically a prodrug of the anabolic-androgenic steroid nandrolone. This compound is valued for its controlled-release profile and enhanced pharmacokinetics, making it a critical intermediate in advanced pharmaceutical synthesis. It is primarily required by manufacturers in the pharmaceutical and research sectors for developing long-acting therapeutic agents and conducting metabolic studies.

Application

• Pharmaceutical Intermediate: Key starting material or intermediate in the synthesis of long-acting anabolic steroid medications.
• Research & Development: Used in preclinical and clinical research to study androgen receptor modulation, pharmacokinetics, and metabolic pathways.
• Hormone Therapy: Serves as a prodrug in formulations designed for the treatment of conditions like anemia, osteoporosis, and muscle-wasting diseases.
• Veterinary Medicine: Employed in the development of growth-promoting and therapeutic agents for livestock and companion animals.
• Reference Standard: Utilized as a high-purity analytical standard in quality control laboratories for HPLC, GC-MS, or other chromatographic methods.
• Biochemical Studies: Applied in vitro and in vivo studies to investigate the effects of sustained androgen delivery on tissue and cellular functions.
