Description

17-Epi-Nandrolone is a synthetic steroid derivative and a stereoisomer of the anabolic steroid nandrolone. This compound is of significant interest in pharmaceutical research and development, particularly for studying structure-activity relationships and metabolic pathways of steroid hormones. It serves as a critical reference standard and intermediate for researchers and manufacturers in the pharmaceutical, biotechnology, and analytical chemistry sectors who require high-purity, well-characterized compounds for their work.

Application

• Pharmaceutical Reference Standard: Used for analytical method development, validation, and quality control (QC/QA) in steroid hormone analysis.
• Biochemical Research: Serves as a key intermediate or metabolite analog in steroid metabolism and endocrinology studies.
• Active Pharmaceutical Ingredient (API) Intermediate: Utilized in the synthetic pathways for developing novel steroid-based therapeutics.
• Doping Control Analysis: Acts as a critical calibration standard in sports anti-doping laboratories for the detection of anabolic agents.
• Academic and Industrial R&D: Employed in research exploring new pharmacological activities or chemical modifications of steroid backbones.
