Quality Control

Our N,n-Bis(2-Hydroxyethyl)-4-Phenylenediamine Sulphate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and impurity profiles. Certificates of Analysis (COA) documenting results for assay, related substances, and other critical parameters are available upon request to support your quality assurance protocols.

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 opening to prevent absorption of atmospheric moisture, which can affect product stability and performance.
