Quality Control

Our 9,11-Dehydro-17β-Estradiol 17-Valerate is manufactured under strict quality control protocols to ensure high purity and batch-to-batch consistency, suitable for research and development purposes. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We adhere to cGMP principles where applicable to support our clients' regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
