Quality Control

Our N,n-Bis(2-Hydroxyethyl)-p-Phenylenediamine Sulfate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for industrial and specialty chemical applications. Certificates of Analysis (COA) documenting purity, assay, and impurity profiles are available upon request.

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 light-sensitive and easily oxidized nature, it is recommended to store under an inert atmosphere for long-term preservation and to minimize exposure to air and moisture.
