Quality Control

Our production of this high-purity specialty dye adheres to stringent ISO 9001 quality management principles. Each batch is characterized using advanced analytical techniques including HPLC, NMR, and mass spectrometry to confirm identity and purity. Certificates of Analysis (COA) detailing lot-specific results for assay, absorbance/fluorescence maxima, and impurity profiles are available upon request to support your R&D and quality assurance protocols.

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 desiccated environment to prevent degradation. For long-term stability, consider storage under an inert atmosphere.
