Description

Drostanolone Propionate is a synthetic anabolic-androgenic steroid (AAS) derived from dihydrotestosterone (DHT). It is valued in the pharmaceutical and research sectors for its potent anti-estrogenic and tissue-building properties with relatively low androgenic activity. This compound is primarily utilized in the development of specialized therapeutic agents and in biochemical research. Drostanolone Propionate CAS NO 521-12-0 is a critical intermediate for formulators and researchers requiring high-purity steroid APIs.

Application

• Pharmaceutical Intermediate: Serves as a key active pharmaceutical ingredient (API) in the synthesis of specialized anabolic medications.
• Research Chemical: Used in biochemical and endocrinological studies to investigate androgen receptor interactions and metabolic pathways.
• Hormone Therapy Development: A component in research for developing treatments for conditions like muscle wasting and certain hormone-responsive cancers.
• Reference Standard: Employed as a high-purity analytical standard in quality control laboratories for HPLC, GC-MS, or other chromatographic methods.
• Veterinary Medicine: Potential use in veterinary applications for improving lean muscle mass and appetite in animals.
