Quality Control

Our 2-Anthracenesulfonic Acid derivative is produced under a stringent quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and spectroscopic identification, to ensure it meets precise specifications for use in sensitive applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product stability and performance.
