Quality Control

Our 1-Benzyl-4-Isothiocyanato-1H-Pyrazole is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and MS, to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment. We support cGMP standards for applications requiring higher levels of documentation and traceability.

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 in a dry environment to prevent moisture absorption and decomposition. Keep away from heat and incompatible materials.
