Quality Control

Every batch of 3-Bromo-1,2-Diaminobenzene is manufactured under a strict quality management system. We employ advanced analytical techniques, including HPLC, GC, and NMR, to ensure identity, purity, and consistency. Our products are suitable for demanding applications, and a comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee traceability and compliance with your specifications.

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 heat, sparks, and open flames.
