Quality Control

Our N,N,N',N'-Tetramethyl-1,2-Diaminopropane is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) and titration methods, to ensure it meets the highest standards of purity and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed specifications.

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 and highly volatile nature, the container must be kept tightly sealed after each use to prevent moisture absorption and evaporation. Keep away from heat, sparks, and open flames.
