Quality Control

Every batch of Trimethylphenylammonium-D9 Iodide is produced and tested under stringent quality management protocols to ensure exceptional isotopic purity and chemical integrity. Our products undergo rigorous quality testing, including NMR and MS analysis, to ensure compliance with the high standards required for analytical and research applications. Certificates of Analysis (COA) detailing isotopic enrichment, chemical purity, and specific test results are available upon request.

Storage

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