Quality Control

Every batch of 2,3-Dihydrocinnolin-4(1H)-One Hydrochloride is manufactured under strict quality management systems. Our products undergo rigorous analytical testing, including HPLC, NMR, and elemental analysis, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications and test results are provided with each shipment and are available upon request.

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.
