Quality Control

Our Bis(4-Isopropylphenyl)Iodonium Hexafluorophosphate is manufactured under stringent quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR, to ensure compliance with high-grade specifications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and performance consistency for your critical applications.

Storage

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