Quality Control

Our 2-(2-Hydroxy)Ethyl-p-Phenylene Diamino Sulfate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure high purity, consistent composition, and batch-to-batch reliability. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided and 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 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.
