Quality Control

Our N,2-Dimethyl-1,3-Propanediamine is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the specifications required for industrial and fine chemical applications. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee supply reliability and product integrity.

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 to prevent absorption of atmospheric moisture and carbon dioxide, which can affect product quality.
