Quality Control

Our n-[3-(Dimethylamino)Propyl]-N'-[3-[[3-(Dimethylamino)Propyl]Amino]Propyl]Propane-1,3-Diamine is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and industry standards. Comprehensive Certificates of Analysis (COA) documenting all critical parameters are provided with every shipment to guarantee traceability and consistency for your production processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after initial use to prevent absorption of atmospheric moisture and carbon dioxide, which can affect product quality. Keep away from strong acids and oxidizing agents.
