Quality Control

Our n-(2-Aminoethyl)-1,3-Propanediamine is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay by titration and impurity profile analysis by gas chromatography (GC), to ensure it meets precise specifications for industrial and fine chemical applications. A comprehensive Certificate of Analysis (COA) detailing purity, water content, and other critical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and a strong alkali; containers must be kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide. Keep away from strong acids and oxidizing agents.
