Quality Control

Every batch of Bis[2-[(2-Methyl-1-Oxoallyl)Oxy]Ethyl] 2,5-Bis(Chloroformyl)Terephthalate undergoes rigorous analytical testing to ensure consistency and high purity suitable for sensitive polymerization reactions. Our quality assurance protocol includes identity confirmation, purity assay, and critical impurity profiling. Certificates of Analysis (COA) documenting all test results are available upon request to support your quality management and regulatory needs.

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 (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
