Quality Control

Our 2,3-Dihydro-6-Isothiocyanato-1,4-Phthalazinedione is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including HPLC for assay and impurity profiling, IR and NMR for structural confirmation, and loss on drying for moisture content. Certificates of Analysis (COA) documenting all test results are provided with every shipment to support your quality assurance and regulatory requirements.

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. Keep away from incompatible materials.
