Quality Control

Our Triethylmethylammonium Tetrafluoroborate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets the high standards required for research and industrial applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment and is available upon request.

Storage

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