Quality Control

Our n-(3-Aminopropyl)-N'-Methylpropane-1,3-Diamine is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets the high-purity standards required for industrial and fine chemical synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee consistency and traceability.

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); containers must be kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide, which can degrade quality.
