Quality Control

Our 2,5-Dibromopyridinium Hydrogen Sulphate is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure consistency and compliance with research and development standards. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment.

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.
