Quality Control

Our Bathocuproine-3,3'-Disulfonic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity verification and spectroscopic methods for identity confirmation, to ensure it meets the high standards required for analytical and research applications. A 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 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 performance. For long-term storage, consider desiccated conditions.
