Quality Control

Our 2(1H)-Pyrazinone, 5-Fluoro- is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity suitable for research and development. We adhere to current Good Manufacturing Practices (cGMP) where applicable. Comprehensive analytical testing, including HPLC, NMR, and MS, is performed to verify identity and purity. A Certificate of Analysis (COA) detailing all specifications is provided with each 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 to prevent moisture absorption, which may affect stability and purity. Keep away from incompatible materials.
