Quality Control

Our Azobenzene-2-Carboxylic Acid is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing including HPLC for purity, NMR and IR for structural confirmation, and residual solvent analysis to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, handling and packaging should minimize exposure to strong light sources.
