Quality Control

Our (1R,2R)-N,N'-Di-p-Toluenesulfonyl-1,2-Diphenyl-1,2-Ethylenediamine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral HPLC and NMR, to ensure high chemical and enantiomeric purity suitable for demanding synthetic applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment.

Storage

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