Quality Control

Our (1R,2R)-1,2-Bis(2-Hydroxyphenyl)Ethylenediamine, 95% is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chiral purity verification by HPLC, to ensure it meets the specified 95% minimum purity and consistent performance. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are available upon request.

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 and easily oxidized nature, it is recommended to handle under an inert atmosphere (e.g., nitrogen or argon) for long-term storage and to minimize exposure to air and moisture during use.
