Quality Control

Our Bis(3,5-Dibromo-4-Allyloxyphenyl) Sulfone is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for use in sensitive polymer applications. A Certificate of Analysis (COA) detailing batch-specific results is provided with each shipment to guarantee traceability and consistency.

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). Keep away from heat sources and incompatible materials. Due to its light-sensitive nature, containers should be kept in the original packaging or opaque containers until use.
