Quality Control

Our (4-(n-Cyclopentylsulfamoyl)-3,5-Dimethylphenyl)Boronic Acid is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and elemental analysis, to ensure high purity and batch-to-batch consistency suitable for sensitive synthetic applications. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing all specifications and test results.

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 nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation.
