Quality Control

Our production of Cyclo-(Dioctylpyrophosphato-O,O)-Bis-(2-Ethylhexanolato)-Zirconium adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot is analyzed against established specifications for critical parameters including zirconium content, ligand ratio, and viscosity. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and relevant physical properties is provided with every shipment to support your quality assurance and regulatory compliance needs.

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). Due to its hygroscopic and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) after opening to maintain product integrity and prevent moisture absorption and degradation.
