Quality Control

Our 2,7-Di-tert-Butyl-4,5-Pyrenediketone is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and NMR/IR for structural confirmation, to ensure it meets the high-purity standards required for sensitive R&D and electronic applications. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its light-sensitive nature and propensity to be easily oxidized, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation of quality.
