Quality Control

Our Azobenzene-4,4'-Dicarboxylic Acid Dimethyl Ester is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and FT-IR, to ensure high chemical purity and structural integrity. Certificates of Analysis (COA) with detailed chromatographic data are provided to guarantee batch-to-batch consistency and support your R&D and production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and incompatible materials. Due to its light-sensitive nature, handling should be performed under subdued lighting where practical.
