Quality Control

Our Disodium 2-(1,3-Dioxoinden-2-Yl)Quinoline-6,8-Disulfonate 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 residual solvent analysis, to ensure it meets precise specifications. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance protocols.

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 opening to prevent absorption of atmospheric moisture, which can affect product stability and performance.
