Description

19-Nortestosterone Acetate is a synthetic anabolic-androgenic steroid (AAS) derivative, specifically the 17β-acetate ester of nandrolone. This compound is valued for its role as a key pharmaceutical intermediate in the synthesis of active pharmaceutical ingredients (APIs) and for research applications in endocrinology and metabolism. It is primarily required by manufacturers in the pharmaceutical industry, research institutions, and by developers of performance-enhancing compounds seeking a controlled and reliable raw material source.

Application

• Pharmaceutical Intermediate: Critical starting material or precursor in the multi-step synthesis of more complex steroid-based APIs.
• Research & Development: Used in biochemical and pharmacological studies to investigate anabolic pathways, receptor binding, and metabolic effects.
• Reference Standard: Serves as an analytical standard in quality control laboratories for method development and impurity profiling.
• Veterinary Medicine: Potential component in the development of formulations for animal growth promotion or therapeutic applications under strict regulatory oversight.
