Quality Control

Our DL-Lysine Hydrochloride is produced under a stringent quality management system. Each batch is tested to ensure it meets exacting specifications for identity, purity, and safety, aligning with pharmaceutical and food-grade standards. Comprehensive Certificates of Analysis (COA) documenting all critical parameters are available upon request 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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect stability and handling properties.
