Quality Control

Our 4-Azidophenylalanyl-Alanyl-Glycyl-Glycine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, MS for identity confirmation, and NMR for structural verification, to ensure compliance with research-grade standards. 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 at -20°C or below in a dry, freezer environment. This product is hygroscopic (moisture-sensitive) and light-sensitive. Allow the sealed vial to equilibrate to room temperature before opening to minimize moisture condensation. For long-term storage, keep desiccated under an inert atmosphere.
