Quality Control

Our N2-[n-(n-Acetyl-L-Leucyl)-L-Leucyl]-L-Arginine Sulphate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR and MS, to ensure it meets the high standards required for pharmaceutical R&D. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

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.
