Quality Control

Our Ethyl [2-Methyl-3-(Chlorosulfonyl)Phenoxy]Acetate is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets the high standards required for research and synthesis. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its nature as a strong acid/organic solvent derivative, keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents. Keep the container tightly sealed when not in use to prevent moisture absorption.
