Quality Control

Our 4,4'-Diazidodiphenyl Ethane is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity. All products undergo rigorous analytical testing, including HPLC and NMR, to verify identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, moisture content, and impurity profiles is provided with each shipment to support your quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from all light exposure. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C) under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation. Keep away from heat, sparks, open flames, and incompatible materials. This material is moisture-sensitive and should be handled in a dry environment.
