Quality Control

Our 3,4'-Biphenyldiamine is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including HPLC, GC, and NMR to verify identity, potency, and impurity profiles. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing all relevant specifications. Our quality management system is designed to meet the rigorous demands of industrial and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, open flames, and incompatible materials such as strong oxidizing agents. Due to its light-sensitive nature, containers should be amber-colored or stored in light-resistant secondary packaging.
