Quality Control

Our 2-(4-Methylphenoxy)Ethanesulfonyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR, to ensure it meets the high standards required for research and process chemistry. Certificates of Analysis (COA) with detailed chromatographic data are provided for every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place. Recommended storage temperature is 2-8°C for long-term stability. Keep away from strong acids, bases, and oxidizing agents.
