Quality Control

Our Pyrazinamine, 5,6-Difluoro-3-Methoxy- (9Ci) is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and MS, to ensure high purity and batch-to-batch consistency. Certificates of Analysis (COA) detailing all specifications 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 a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
