Quality Control

Our 1,2-Diphenylethylenediamine is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure high chemical purity and enantiomeric excess (e.e.) suitable for demanding synthetic applications. A Certificate of Analysis (COA) detailing purity, chiral purity, and other critical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, the container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation. Recommended storage temperature is 2-8°C for long-term stability.
