Description

5-Dihydro-19-Nortestosterone is a potent synthetic anabolic-androgenic steroid (AAS) derived from nandrolone. This compound is of significant interest in pharmaceutical research and development for its unique metabolic profile and tissue-selective effects. It serves as a critical intermediate and reference standard for researchers in the pharmaceutical, biotechnology, and academic sectors focusing on endocrinology, metabolism, and performance-enhancing substance analysis.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of more complex anabolic agents and hormone therapies.
• Reference Standard: Used in analytical laboratories for method development, calibration, and quality control testing of related steroid compounds.
• Biomedical Research: Employed in preclinical studies to investigate androgen receptor interactions, myotrophic effects, and metabolic pathways.
• Doping Control: Acts as a critical standard for anti-doping agencies and testing laboratories to detect and confirm the presence of banned anabolic agents.
• Metabolite Studies: Used in research to study the biotransformation, pharmacokinetics, and detection windows of nandrolone and its derivatives.
