Quality Control

Our Benzenesulfonamide, 4-Diazenyl- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with key parameters such as assay (HPLC), identification (IR, NMR), and impurity profiles. Our quality commitment aligns with cGMP principles for research and fine chemical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its light-sensitive nature and tendency to be easily oxidized, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flame.
