Quality Control

Our 1,2-Cyclobutanediamine,3-Methyl-(9Ci) is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is characterized using advanced analytical techniques including chiral HPLC, GC, and NMR to confirm identity, enantiomeric excess, and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

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