Quality Control

Our production of 2-[[4-(Dimethylamino)Phenyl]Azo]-1,3-Dimethyl-1H-Imidazolium Methyl Sulphate adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and consistent performance in downstream applications. Certificates of Analysis (COA) documenting all critical quality parameters are provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality and performance.
