Quality Control

Our Sodium 4-[[4-[[4-(2-Hydroxybutoxy)-m-Tolyl]Azo]Phenyl]Amino]-3-Nitro-n-(Phenylsulphonyl)Benzenesulphonamidate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for use in sensitive synthesis processes. Certificates of Analysis (COA) documenting purity, heavy metals, and related substance profiles are available upon request to support your quality assurance protocols.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after use to prevent moisture absorption, which can affect stability and handling properties. Keep away from incompatible materials such as strong oxidizing agents.
