Quality Control

Our 4-Bromo-1,2-Benzenediamine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting standards for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles 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, well-ventilated place at room temperature (15-25°C). Due to its nature as an aromatic amine that is easily oxidized (store under inert atmosphere) and light-sensitive (store away from light), prolonged exposure to air, moisture, or light should be avoided. Keep away from strong oxidizing agents.
