Quality Control

Our 2-Oxo-3,4-Dihydro-1H-Quinoline-6-Sulfonic Acid Hydrate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and KF titration for water content, to ensure it meets exacting standards for research and industrial use. A detailed Certificate of Analysis (COA) is provided with every shipment, guaranteeing traceability and consistent quality.

Storage

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