Description

Epristeride CAS NO 119169-78-7 is a potent and selective inhibitor of the enzyme 5α-reductase type II. This compound is of significant value in pharmaceutical research and development, particularly for targeting androgen-dependent conditions. It is primarily utilized by pharmaceutical companies and research institutions focused on developing treatments for benign prostatic hyperplasia (BPH) and other disorders related to dihydrotestosterone (DHT) activity.

Application

• Primary active pharmaceutical ingredient (API) in the development of treatments for benign prostatic hyperplasia (BPH).
• Key reference standard and intermediate in pharmaceutical research for androgen-related pathways.
• Biochemical tool for in vitro and in vivo studies investigating 5α-reductase enzyme inhibition.
• Critical component in the synthesis and formulation of targeted therapeutic agents.
• Used in preclinical and clinical research to study pharmacokinetics and pharmacodynamics.

Quality Control

Our Epristeride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, identity confirmation by IR and NMR spectroscopy, and residual solvent analysis to ensure it meets high-grade pharmaceutical standards. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants.
