Quality Control

Our 1-tert-Butyl-2,2,4,4,4-Pentakis(Dimethylamino)-2Lambda5,4Lambda5-Catenadi(Phosphazene) is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including NMR (1H, 31P) and HPLC analysis, to confirm identity and assay. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (argon or nitrogen) after opening to prevent degradation. Keep away from heat and incompatible materials.
