Quality Control

Every batch of n-Phenyliminophosphoric Acid Trichloride is manufactured and tested under a strict quality management system. We ensure product integrity through comprehensive analytical protocols including NMR, IR, and HPLC analysis. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee consistency and support your regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening. Keep away from strong acids and incompatible organic solvents.
