Quality Control

Our 1(2H)-Phthalazinone, 4-Amino- is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques, including HPLC, NMR, and mass spectrometry, for comprehensive characterization and impurity profiling. Certificates of Analysis (COA) detailing purity, identity, and specific test results are provided with every shipment to support your quality assurance and regulatory needs.

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 after each use to prevent degradation from atmospheric moisture.
