Quality Control

Our n-Phenyl-2-Biphenylamine is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC and GC analysis, to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from strong oxidizing agents.
