Quality Control

Our Hexa(p-Carboxyphenoxy)Cyclotriphosphazene is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR spectroscopy, to ensure consistency and compliance with high-purity standards. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under dry, inert conditions to prevent degradation.
