Quality Control

Our 2-Chloro-4-Hydrazinylbenzonitrile Hydrochloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, identity confirmation by IR and NMR spectroscopy, and residual solvent analysis, to ensure it meets the high standards required for research and development. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect stability and performance.
