Quality Control

Our 2-Ethyl-7-Hydroxy-1,2-Benzisoxazole Tetrafluoroborate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency, meeting the high standards required for research and industrial synthesis. Certificates of Analysis (COA) with detailed specifications from HPLC, NMR, and other relevant methods are provided with every shipment.

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 after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
