Quality Control

Our Estra-1,3,5(10)-Trien-17-Ol, 3-Methoxy-, Acetate, (17Beta)-(+/-)- is manufactured under strict quality protocols. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing HPLC purity, residual solvents, and other critical parameters are provided with every shipment to support your quality systems and regulatory requirements.

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.
