Quality Control

Every batch of Bis(3-Allyl-4-Hydroxyphenyl)Sulfone is manufactured and tested under a strict quality management system. We ensure the product meets high-purity standards suitable for demanding industrial and research applications. Comprehensive testing includes identity confirmation, purity assay, and impurity profiling. A Certificate of Analysis (COA) detailing all specifications and test results is provided with each shipment and is available upon request.

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). Due to its properties of being light-sensitive and easily oxidized, it is recommended to store the material under an inert atmosphere (e.g., nitrogen) for long-term preservation to maintain stability and prevent degradation. Keep away from heat, sparks, and open flames.
