Quality Control

Our Benzenesulfonamide, o-Nitroso- (7Ci) is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing including HPLC for purity, IR for identification, and loss on drying to confirm specifications. Certificates of Analysis (COA) documenting all critical parameters are provided to ensure traceability and compliance with your research or production requirements.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
