Quality Control

Our Poly(Bis(Methoxy)Phosphazene) is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Quality is verified through a suite of analytical techniques including NMR, GPC, and FTIR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing purity, molecular weight distribution, and other critical parameters is provided with each shipment to support your research and quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) in a desiccator to prevent degradation upon exposure to atmospheric moisture.
