Quality Control

Our (1S,2S)-1,2-Dicyclohexylethane-1,2-Diamine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity verification by HPLC, to ensure compliance with high-grade specifications for research and industrial use. Certificates of Analysis (COA) detailing identity, purity, and enantiomeric excess are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality. For long-term storage, consider using an inert atmosphere.
