Quality Control

Our R3=Tms is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and spectroscopic identification, to ensure it meets the high standards required for research and industrial synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming identity, purity, and conformance to agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation. Recommended long-term storage temperature is 2-8°C.
