Quality Control

Our 1,3-Bis[2,6-Bis(1-Ethylpropyl)Phenyl]Imidazolium Chloride is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including NMR, HPLC, and elemental analysis, to ensure high purity and consistent performance as a catalyst precursor. Certificates of Analysis (COA) detailing all specifications are provided with every shipment.

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 nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation.
