Quality Control

Our Trimethyl-D9-Sulfonium Iodide is manufactured under strict quality control protocols to ensure high isotopic purity and chemical integrity. Each batch is characterized by advanced analytical techniques including NMR and Mass Spectrometry. A comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (typically >98 atom % D), chemical purity, and other critical parameters is provided with every shipment to support your research and compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under a dry inert atmosphere to maintain stability and prevent decomposition.
