Quality Control

Our 3-o-Benzyl Estratetraenol is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by spectroscopic methods, to ensure it meets the high standards required for pharmaceutical research. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting critical quality attributes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and stored in a dark environment to maintain stability and purity.
