Quality Control

Our production of this xanthene dye adheres to strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity and spectrophotometry for color strength verification, to ensure it meets precise customer specifications. A detailed Certificate of Analysis (COA) documenting identity, purity, and impurity profiles is provided with each shipment to guarantee traceability and compliance.

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 tightly sealed after use to prevent absorption of atmospheric moisture, which can affect product performance.
