Quality Control

Our D-Ornithine Monohydrate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets stringent specifications for identity, purity, and enantiomeric excess. Certificates of Analysis (COA) detailing results for assay, optical rotation, heavy metals, residual solvents, and microbiological parameters are provided with every shipment. We support compliance with cGMP, ISO, and relevant pharmacopeial guidelines (USP/EP) for pharmaceutical-grade applications.

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