Quality Control

Our 4-sec-Butylidene-1,2-Diphenyl-3,5-Pyrazolidinedione is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC and NMR, to ensure high purity and consistent performance for research and synthesis applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every 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 (typically 15-25°C). Due to its light-sensitive nature and propensity for oxidation, prolonged exposure to light and air should be avoided. For long-term storage, consider an inert atmosphere.
