Quality Control

Our 4,4'-(1,2-Ethanediylidene)-Bis(2,6-Dimethyl-2,5-Cyclohexadien-1-One) is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (IR, NMR). Certificates of Analysis (COA) documenting all critical parameters are available upon request to ensure full traceability and compliance with your research or production specifications.

Storage

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