Quality Control

Our Hfpo Hexamer Acid is manufactured under stringent quality systems. Every batch undergoes comprehensive analytical testing, including NMR (19F, 1H), FT-IR, and titration methods, to confirm identity, purity, and acid value. We provide full traceability and Certificates of Analysis (COA) with each shipment, ensuring compliance with your precise research and production specifications.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended long-term storage temperature is 2-8°C. Keep away from strong bases and oxidizing agents.
