Quality Control

Our production of this dye intermediate adheres to stringent quality management systems to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including HPLC for purity, spectrophotometry for color strength, and elemental analysis. A detailed Certificate of Analysis (COA) documenting identity, purity, and impurity profiles is provided with every 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 tightly sealed after opening to prevent absorption of atmospheric moisture, which may affect product stability and performance.
