Quality Control

Our N,n-Dimethylpropanediamine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) for purity and identity confirmation, to ensure it meets precise specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and batch-to-batch consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed to prevent moisture absorption and evaporation. Keep away from heat, sparks, and open flame. Store separately from strong acids and oxidizers.
