Quality Control

Our H-Ala-His-Lys-Oh is produced under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for research applications. Each lot undergoes comprehensive analytical testing including HPLC for purity, MS for identity confirmation, and chiral analysis. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, ensuring full traceability and compliance with your research or development protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed in a dry environment to prevent degradation. For long-term storage, consider desiccants or inert atmosphere.
