Quality Control

Our Gly-Dl-Leu-Dl-Ala is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity verification and identity confirmation by spectroscopic methods, to ensure it meets the high standards required for research and development. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment and is available upon request.

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 tightly sealed in a dry environment to prevent product degradation. For long-term storage, consider using desiccants.
