Quality Control

Our Rose Bengal Diacetate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial use. 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 (moisture-sensitive) nature, the container must be kept tightly sealed in a low-humidity environment. For long-term storage, consider using a desiccant.
