Quality Control

Our Poly(Methylene-4-Phenylene-Methylene Dimethylaminoethylene Diamine) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistent purity, molecular weight distribution, and functional group content. A comprehensive Certificate of Analysis (COA) detailing assay, identity, and impurity profiles is provided with every shipment to guarantee it meets your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept in a cool, dry place with minimal humidity fluctuation. Recommended storage temperature is between 15°C and 25°C. Keep the container tightly sealed after each use to prevent moisture absorption and degradation.
