Quality Control

Our Hexanitrodiphenylamine is manufactured under strict process controls to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical techniques including HPLC, IR spectroscopy, and titration methods. A detailed Certificate of Analysis (COA) providing purity, impurity profile, and physical data is provided with each shipment to meet the stringent requirements of industrial and research applications.

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 nature as an easily oxidized compound, it is recommended to store under an inert atmosphere for long-term stability. Keep container tightly sealed when not in use to minimize moisture uptake and decomposition.
