Quality Control

Our 2-m-Tolyl-Ethanesulfonyl Chloride is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and GC analysis, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available for every shipment, supporting your regulatory and R&D requirements.

Storage

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