Quality Control

Our Pyridazine, 4-Bromo- (9Ci) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, GC, NMR, and mass spectrometry, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment and are available upon request.

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 and under an inert atmosphere for long-term storage to prevent degradation.
