Quality Control

Our 2-Propenoic Acid, 2-Methyl-, Azobis(4,1-Phenyleneoxy-6,1-Hexanediyl) Ester (9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for polymerization applications. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C/59-77°F) under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation and thermal decomposition. Keep away from heat, sparks, open flames, and incompatible materials. This material is light-sensitive and easily oxidized.
