Quality Control

Our L-Proline Sodium Salt is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for research and industrial applications. Certificates of Analysis (COA) detailing purity, identity, and specific impurity profiles are available upon request. We can supply material compliant with various internal specifications, including those for pharmaceutical intermediates (ICH guidelines) and biochemical use.

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 minimize exposure to atmospheric moisture. For long-term storage, consider using a desiccant.
