Quality Control

Our 8-Isoquinolinesulfonic Acid, 5-Bromo- is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay (HPLC), impurity profile, and residual solvent analysis. Our quality commitment supports applications requiring high-purity intermediates for research and development.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption. Keep away from incompatible materials.
