Quality Control

Our (1S,2S)-1,2-Bis(2-Methoxyphenyl)Ethane-1,2-Diamine is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chiral purity verification by HPLC, to ensure it meets the specified minimum 97% purity and consistent performance. Certificates of Analysis (COA) with detailed chromatographic data are available upon request to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 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.
