Quality Control

Our 4-Hydrazino-7-Nitrobenzofurazan is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity assessment and spectroscopic methods for identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation. For long-term storage, consider using a desiccator.
