Quality Control

Our N,N'-Dimethyl-1,3-propanediamine is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets exacting specifications for industrial and fine chemical applications. Certificates of Analysis (COA) documenting batch-specific results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Due to its hygroscopic and highly volatile nature, containers should be kept tightly sealed under a dry, inert atmosphere to prevent moisture absorption and degradation. Recommended storage temperature is 15-25°C.
