Quality Control

Our 6-Methyl-2-oxo-1,2-dihydroquinoline-3-carboxylic acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and MS, to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment, and we support custom purity grades to meet specific project requirements from research to commercial scale.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
