Quality Control

Our Disodium 3-(2-Hydroxyphenyl)-8-Sulphonatobenzo[F]Quinoline-1-Carboxylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and elemental analysis. We provide comprehensive Certificates of Analysis (COA) with each shipment to ensure traceability and compliance with your research or production specifications.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
