Quality Control

Our production of Disodium 2-(2,3-Dihydro-1,3-Dioxosulphonato-1H-Inden-2-Yl)Quinolinesulphonate adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. All products undergo rigorous analytical testing, including HPLC for assay and impurity profiling, to meet exacting customer specifications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and related substances is provided with each shipment to support your quality assurance and regulatory compliance needs.

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 product stability and performance. Keep away from incompatible materials.
