Quality Control

Our Trimethyloxonium-D9 Tetrafluoroborate is manufactured under controlled conditions to ensure high isotopic purity and chemical integrity. Each batch undergoes rigorous analytical testing, including NMR and mass spectrometry, to confirm deuterium incorporation and chemical purity. Certificates of Analysis (COA) detailing isotopic enrichment, assay, and impurity profiles are available upon request to support your quality assurance protocols.

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 must be kept tightly sealed in a desiccated environment. Handle and store under an inert atmosphere such as argon or nitrogen for long-term stability.
