Quality Control

Our Tetramethyl 5,5'-[(1,4-Dioxo-1,4-Butanediyl)Diimino]Bisisophthalate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets exacting research and production-grade specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be opaque or stored in dark conditions.
