Quality Control

Our 5-Acridinesulfonic Acid (1Ci) is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity verification and spectroscopic methods for structural confirmation, to ensure it meets the high standards required for research and development. A detailed Certificate of Analysis (COA) documenting identity, purity, and impurity profile is provided with every shipment to guarantee traceability and consistency for your critical applications.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed and consideration should be given to storage under an inert atmosphere for long-term preservation of quality.
