Quality Control

Every batch of 2H-1,4-Benzoxazin-2-One,3,4-Dihydro-3-Hydroxy-(9Ci) is manufactured under a strict quality management system. Our products undergo rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency meet the exacting standards required for research and development. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
