Quality Control

Our H-Lys-Arg-Thr-Leu-Arg-Arg-Oh is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and MS for identity confirmation, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) detailing purity, identity, and other critical parameters are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. Due to its hygroscopic nature, the product should be allowed to equilibrate to room temperature in a desiccator before opening to prevent moisture absorption. For long-term storage, keep containers sealed under an inert atmosphere such as argon or nitrogen.
