Quality Control

Our 1,8-Dihydroxypyrido[2,3-D]Pyridazin-5-One is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for research and development applications. Each lot is analyzed with modern analytical techniques, including HPLC and NMR, to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment and is 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.
