Quality Control

Our (1R,2R)-(+)-1,2-Bis(4-Dimethylaminophenyl)Ethylenediaminetetrahydrochloride is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chiral purity verification by HPLC and structural confirmation. Certificates of Analysis (COA) detailing specific results for identity, purity, and chiral excess are available 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 nature, the container should be kept in a desiccated environment to prevent moisture absorption, which can affect stability and handling properties.
