Quality Control

Our (4-(n-Cyclopentylsulfamoyl)-3-Fluorophenyl)Boronic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, NMR for structural confirmation, and Karl Fischer titration for moisture content, to ensure it meets the high standards required for research and process chemistry. Certificates of Analysis (COA) with full traceability are provided with every shipment.

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.
