Quality Control

Our Proline, 3-Ethyl-, Methyl Ester (9Ci) is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chiral purity assessment by HPLC, to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) documenting identity, purity, and chiral integrity are available upon request.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
