Quality Control

Every batch of our N,N'-Diphenyl-N,N'-Bis(4'-(N,n-Bis(Naphth-1-Yl)-Amino)-Biphenyl-4-Yl)-Benzidine is synthesized and purified under controlled conditions to meet the stringent requirements of the electronics industry. We employ advanced analytical techniques, including HPLC, NMR, and mass spectrometry, to ensure high purity and batch-to-batch consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at room temperature (15-25°C) under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation. Keep away from heat and incompatible materials. For long-term storage, consider refrigeration at 2-8°C under inert gas.
