Quality Control

Our 2H-1-Benzopyran-2-One,7-Isocyanato-3-Phenyl is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and IR & NMR for structural confirmation, to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
