Quality Control

Our L-Lysine Hydrobromide is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including identification, assay, and impurity profiling, to ensure it meets stringent specifications for pharmaceutical and food-grade applications. A Certificate of Analysis (COA) documenting purity, optical rotation, and residual solvent levels is provided with every shipment to guarantee traceability and compliance.

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 opening to prevent moisture absorption and caking. Keep away from incompatible materials.
