Quality Control

Our 4-Oxo-3,4-Dihydro-Phthalazine-1-Carboxylic Acid Hydrazide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles 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 a controlled room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, it is recommended to handle under an inert atmosphere for long-term storage and to minimize exposure to air and moisture.
