Quality Control

Our 2-Cyclopentene-1-Carboxylicacid,1-Amino-,Ethylester(9Ci) is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and chiral purity assessment, to ensure it meets the high standards required for research and development. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee traceability and support your regulatory documentation.

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 after opening to prevent moisture absorption, which may affect stability and purity. Keep away from incompatible materials.
