Quality Control

Our N,N'-Bis(3-(Ethylamino)Propyl)-1,7-Heptanediamine is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing, including assay by titration and impurity profile analysis via GC or HPLC, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance and regulatory compliance needs.

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 each use to prevent absorption of atmospheric moisture, which can affect product quality.
