Quality Control

Our Bis(4-tert-Butylphenyl)Iodonium Hexafluorophosphate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, NMR for structural confirmation, and ICP-MS for trace metal analysis, to ensure it meets the stringent requirements of photoresist and polymer formulation applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 15-25°C. This material is hygroscopic (moisture-sensitive) and must be kept under dry, inert conditions such as in a desiccator or under a nitrogen atmosphere to prevent decomposition. Keep away from strong bases and incompatible materials.
