Quality Control

Our o-(2-Methoxyethoxy)-Benzene Sulfonyl Isocyanate is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR spectroscopy, to ensure it meets the high standards required for research and process chemistry. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation by atmospheric moisture.
