Quality Control

Our 1R,2R-Bis[(1S)-1-Phenylethyl]-1,2-Diphenyl-1,2-Ethanediamine is manufactured under strict quality management systems to ensure batch-to-batch consistency and high enantiomeric purity. Each lot is characterized by advanced analytical techniques including HPLC, NMR, and optical rotation measurement. A comprehensive Certificate of Analysis (COA) detailing purity, enantiomeric excess, and identity is provided with every shipment to support your quality assurance protocols.

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 nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
