Quality Control

Our 2,5-Dibromo-1,4-Phenylenediamine is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled 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 stability. Keep away from strong oxidizing agents.
