Quality Control

Our (4-Iodophenyl)Diphenylsulfonium Triflate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure high consistency and performance for critical applications. Certificates of Analysis (COA) detailing lot-specific results are available upon request.

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 light-sensitive; containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) in a desiccator to prevent degradation and maintain efficacy.
