Quality Control

Our 2,2-(1,3,5,7-Tetraoxo-5,7-Dihydropyrrolo(3,4-F)Isoindole-2,6(1H,3H)Diyl)Dibenzoic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR, to ensure it meets exacting research and industrial-grade specifications. Comprehensive Certificates of Analysis (COA) detailing all test results are provided to guarantee traceability, consistency, and compliance with your project requirements.

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 when not in use to prevent degradation. Keep away from incompatible materials such as strong bases and strong oxidizing agents.
