Quality Control

Every batch of our 1,3-Dioxo-2-[6-(6-Methyl-7-Sulfo-2-Benzothiazolyl)-2-Quinolinyl]-2,3-Dihydro-1H-Indene-5-Carboxylic Acid is produced and tested under a strict quality management system. We ensure high purity and batch-to-batch consistency through advanced analytical techniques including HPLC, NMR, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment 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 degradation from atmospheric moisture. Keep away from incompatible materials.
