Quality Control

Our production of N,n-Bis(4-Sulfobutyl)-3-Methylaniline,Disodiumsalt adheres to a stringent quality management system to ensure batch-to-batch consistency and high purity. Each lot is analyzed against comprehensive specifications using advanced techniques like HPLC and NMR. A Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment, ensuring full traceability and compliance with customer and industry requirements.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
