Quality Control

Our 2,6-Dichloro-1,4-Phenylenediamine is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets defined specifications for purity, identity, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing results from HPLC, IR, and other relevant tests is provided with every shipment to guarantee traceability and compliance with your requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents.
