Quality Control

Our (4-Bromo-1H-Pyrazol-1-Yl)Acetonitrile is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is subjected to rigorous analytical testing, including HPLC, NMR, and GC-MS, to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory needs.

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). This compound is hygroscopic (moisture-sensitive); therefore, containers must be kept tightly sealed to exclude moisture. Keep away from incompatible materials such as strong acids, bases, and oxidizing agents.
