Quality Control

Our 1H-Pyrazole-4-Carbonyl Fluoride, 5-Fluoro-1,3-Dimethyl- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and MS, to ensure high purity and consistent chemical identity. Certificates of Analysis (COA) with detailed chromatographic data are 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, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
