Quality Control

Our 33Dichloro44Diaminodiphenylether is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques, including HPLC and GC-MS, to monitor impurities and confirm identity. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and specific impurity limits is provided with each shipment 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). Keep away from strong oxidizing agents, acids, and moisture. Due to its light-sensitive nature, containers should be amber-colored or stored in dark conditions.
