Quality Control

Our N,N'-(2,2-Dimethylpropylidene)Hexamethylenediamine is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, identity confirmation, and impurity profiling, to ensure it meets precise customer specifications and industry standards. Certificates of Analysis (COA) documenting purity, physical properties, and stability 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 a controlled room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) and minimize exposure to air and moisture to maintain product integrity.
