Quality Control

Our 4,4'-Biphenylylenebis(Trimethylammonium) Bis(Methylsulfate) is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and industrial applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee traceability and consistency.

Storage

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