Quality Control

Every batch of Acetyldiethylstilbestrol 2,3,4-Tri-o-Acetyl--D-Glucuronide Methyl Ester is manufactured and tested under strict quality management systems to ensure identity, purity, and consistency. Our products undergo rigorous quality testing, including advanced chromatographic and spectroscopic methods, to ensure compliance with research-grade standards. A comprehensive Certificate of Analysis (COA) detailing purity, identity confirmation, and impurity profiles is available for every lot upon request.

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 desiccants or an inert atmosphere.
