Quality Control

Our 4-Hydroxy-6-Oxo-1-Phenyl-1,6-Dihydro-3-Pyridazinecarboxylic Acid is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity (typically ≥95% by HPLC), residual solvents, and other critical parameters is provided with each shipment to support your quality assurance protocols.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
