Quality Control

Our production of this dye intermediate adheres to strict quality management systems to ensure batch-to-batch consistency and high purity. Every lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling. A detailed Certificate of Analysis (COA) documenting identity, purity, and specific parameters is provided with each shipment to support your quality assurance protocols.

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 when not in use to prevent absorption of atmospheric moisture.
