Quality Control

Our production of this dye intermediate adheres to strict quality management systems to ensure batch-to-batch consistency and purity. Every lot is analyzed using advanced techniques including HPLC and spectrophotometry to verify critical parameters such as color strength, hue, and impurity profile. A comprehensive Certificate of Analysis (COA) detailing assay, identity, and specific tests 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 room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product performance.
