Quality Control

Our 2,3-Benzofurandione, 2-Oxime is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing including HPLC for purity, IR and NMR for structural confirmation, and loss on drying to ensure it meets precise specifications. Certificates of Analysis (COA) documenting all test results are provided with every shipment to guarantee traceability, consistency, and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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. For long-term storage, consider using an inert atmosphere to minimize oxidation.
