Quality Control

Our Dl-Leucyl-Dl-Phenylalanine is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets high-purity standards suitable for research and synthesis. 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 place at 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 degradation. For long-term storage, consider using desiccants.
