Quality Control

Our β-Styrene Sulfonyl Chloride is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets high-purity standards suitable for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing specific results for purity, appearance, and other critical parameters is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from strong bases, oxidizing agents, and sources of ignition.
