Quality Control

Our Aureobasidin S3 is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets the high standards required for research and development. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a desiccated environment to maintain stability and potency.
