Quality Control

Our 6-Bromopenicillanic Acid S-Sulfoxide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for pharmaceutical intermediate applications. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and other critical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed in a dry environment and handled under conditions that minimize exposure to ambient light and humidity to maintain stability and purity.
