Quality Control

Our production of Catechylphosphorotrichloride adheres to stringent in-process controls to ensure batch-to-batch consistency and high chemical purity. Each lot is analyzed using advanced chromatographic and spectroscopic techniques. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

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 sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from strong acids, bases, and oxidizing agents.
