Quality Control

Our 2-Pyrrolidinone,5-Ethenyl-1-Methyl-,(S)-(9Ci) is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including chiral purity determination, to meet the stringent requirements of research and process development. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area 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 stability and performance. Keep away from incompatible materials.
