Quality Control

Every batch of Azoxybenzene-4,4'-Dicarboxylic Acid Diethyl Ester is manufactured and tested under a strict quality management system. Our products undergo rigorous quality testing, including HPLC, NMR, and IR spectroscopy, to ensure compliance with high-purity standards for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat, open flames, and incompatible materials. Due to its light-sensitive nature, prolonged exposure to direct light should be avoided.
