Quality Control

Our Proline, 3-Hydroxy-5-Oxo-, Methyl Ester, Dl-cis- (8Ci) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and chiral analysis, to ensure it meets the exacting standards required for research and synthesis. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available for every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which may affect stability and performance.
