Quality Control

Our Naphthol As-Bi β-L-Fucopyranoside is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including identity confirmation by spectroscopic methods and purity assessment by HPLC, to ensure it meets the high standards required for sensitive diagnostic and research applications. Certificates of Analysis (COA) detailing all specifications are 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). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can affect product stability and performance.
