Quality Control

Our 4-(4-Fluoro-Phenoxy)-Benzenethiol is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by NMR and IR spectroscopy, to ensure it meets the high standards required for research and process chemistry. Certificates of Analysis (COA) detailing all specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its property of being easily oxidized, this material should be stored under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C). Keep the container in a cool, dry, and well-ventilated place, away from incompatible materials such as strong oxidizing agents.
