Quality Control

Our production of 1,3-Benzenediamine, N1,N3-Bis[4-(1,1-Dimethylethyl)Phenyl]- adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and industry benchmarks. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere); therefore, containers should be kept sealed under an inert gas blanket (e.g., nitrogen or argon) after opening to maintain purity and prevent degradation.
