Quality Control

Our 1,3-Dioxo-1H-Benzo[De]Isoquinoline-2(3H)-Acetic Acid Sodium Salt is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting specifications for sensitive applications. Certificates of Analysis (COA) documenting all critical parameters are available upon request, providing full traceability and quality assurance for our global B2B clients.

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.
