Quality Control

Our Potassium (E)-(3-Ethoxy-3-Oxoprop-1-En-1-Yl)Trifluoroborate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR (1H, 11B, 19F) and HPLC analysis, to ensure high chemical purity and structural integrity. Certificates of Analysis (COA) with detailed specifications are provided for every shipment to guarantee batch-to-batch consistency and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from incompatible materials such as strong acids and strong oxidizing agents.
