Quality Control

Our (1S,2S)-1,2-Bis(4-Dimethylaminophenyl)-1,2-Ethanediamine Tetrahydrochloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity verification and impurity profiling, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) detailing purity, enantiomeric excess, and other critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance.
