Quality Control

Our N,N,N',N'-Tetramethyl-2,2-Dimethyl-1,3-Propanediamine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC and titration methods, to ensure it meets precise purity and compositional specifications. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance protocols.

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 easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize moisture uptake.
