Quality Control

Our n-(2-Aminomethylethyl)Propane-1,2-Diamine is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay and impurity profile determination, to ensure it meets precise specifications. A Certificate of Analysis (COA) documenting purity, identity, and other critical parameters is provided with every shipment to guarantee traceability and consistency for your 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). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide, which can degrade quality.
