Quality Control

Our Hydroxypropylbis(n-Hydroxyethyl-Para-Phenylenediamine) is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including assay, impurity profiling, and identity confirmation, to ensure it meets precise customer specifications and industry standards. A comprehensive Certificate of Analysis (COA) detailing purity, physical characteristics, and test results is provided with every 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 (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product quality and stability.
