Quality Control

Our 3-Ethyl-4-Oxo-3,4-Dihydro-Phthalazine-1-Carboxylic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with each shipment, confirming compliance with agreed specifications. For customers with specific regulatory needs, we can support documentation for GMP or ISO-guided applications.

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). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed to minimize exposure to atmospheric humidity. For long-term storage, consider using desiccants.
