Quality Control

Our Triphenylphosphinegold(I) Trifluoromethanesulfonate is manufactured under strict quality protocols to ensure batch-to-batch consistency and high catalytic performance. Each lot is analyzed to confirm identity, purity, and the absence of deleterious metallic impurities. A comprehensive Certificate of Analysis (COA) detailing specifications such as assay (by titration or ICP), residual solvent content, and physical appearance is provided with every shipment to support your quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container should be kept in a desiccator or under an inert atmosphere (e.g., argon or nitrogen) after opening to prevent decomposition.
