Quality Control

Our Erythro-5-Hydroxy-L-Lysine is manufactured under a quality management system and undergoes rigorous analytical testing to ensure high purity and batch-to-batch consistency. Standard quality parameters include assay (HPLC), chiral purity, and control of related substances. A Certificate of Analysis (COA) detailing all test results is provided with each batch to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect stability and handling properties.
