Quality Control

Every batch of our 2-Pyrrolidinone,3,4-Dimethyl-5-Methylene-,cis-(9Ci) undergoes rigorous analytical testing to ensure identity, purity, and consistency. We employ advanced techniques including HPLC, GC, and NMR to verify high chiral purity and control for impurities. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption. Keep away from incompatible materials such as strong oxidizing agents.
