Quality Control

Our N6-Benzoyl-Dl-Lysine is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for research and synthesis. Each lot undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis, and identity confirmation. A Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment to support your quality assurance and regulatory documentation needs.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect stability and handling properties.
