Quality Control

Our α-Isobutylstyrene is produced and handled under a strict quality management system. Each batch is analyzed to ensure it meets high-purity standards suitable for polymerization and synthesis. Key parameters including identity, assay, and impurity profiles are verified. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at room temperature (15-25°C) under an inert atmosphere such as nitrogen, as the material is easily oxidized. Keep away from heat, sparks, and open flame.
