Quality Control

Our 21-Amino-n-[2-[[2-[[2-[(2-Aminoethyl)Amino]Ethyl]Amino]Ethyl]Amino]Ethyl]-9-(1-Hydroxynonyl)-9,12,15,18-Tetraazahenicosanamide is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity, NMR for structural confirmation, and Karl Fischer titration for moisture content, to ensure it meets precise customer specifications. Certificates of Analysis (COA) documenting all test results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
