Quality Control

Our 4-(n-Cyclopropylsulfonamide)Phenylboronic Acid Pinacol Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) with full traceability are provided for every shipment, supporting compliance in regulated environments.

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). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to maintain stability and purity.
