Quality Control

Our 4-Bromo-4'-(Diphenylamino)Biphenyl is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request to support your quality assurance and R&D documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, handling and packaging should minimize exposure to strong light sources.
