Quality Control

Our n-Phenyl-1,4-Naphthalenediamine is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and industry standards. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature (store under inert atmosphere), it is recommended to handle under an inert atmosphere such as nitrogen for long-term storage and to minimize headspace in opened containers.
