Quality Control

Our Diazenesulfonic Acid, (2-Methylphenyl)- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity assessment and spectroscopic methods for structural confirmation, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance and regulatory documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under anhydrous conditions to prevent degradation. Keep away from incompatible materials.
