Quality Control

Our Cyclopropanamine, 2-Methyl-, (1R,2R)- is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including chiral purity analysis by HPLC and GC, to ensure high enantiomeric excess (ee) and chemical purity. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality and regulatory requirements.

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 under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation.
