Quality Control

Our Dl-Lysine Monohydrate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets stringent specifications for identity, purity, and composition. Certificates of Analysis (COA) documenting results for assay, optical rotation, residue on ignition, heavy metals, and related substances are 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). This product is hygroscopic (moisture-sensitive) and must be kept in its original, sealed packaging until use to prevent absorption of atmospheric moisture, which can lead to caking and degradation.
