Quality Control

Our N,N,N',N'-Tetramethyldodecane-1,12-Diamine is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay (GC/HPLC), identity confirmation (IR, NMR), and impurity profiling, to ensure it meets precise customer specifications and industry standards. A Certificate of Analysis (COA) detailing all test results 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). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture and carbon dioxide, which can affect product quality.
