Quality Control

Our n-4-Biphenylyl-n-Hydroxybenzenesulfonamide is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing including HPLC for purity, IR and NMR for structural confirmation, and tests for residual solvents and heavy metals. Certificates of Analysis (COA) documenting all critical specifications are provided and available upon request to ensure traceability and compliance with your internal quality standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation of quality. Keep away from strong oxidizing agents.
