Quality Control

Our production of this reactive dye intermediate adheres to stringent quality control protocols to ensure batch-to-batch consistency and performance reliability. Quality is verified through advanced analytical techniques including HPLC for purity and spectrophotometry for color strength. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical specifications is provided with every shipment to support your quality assurance processes.

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 moisture absorption and degradation. Keep away from incompatible materials.
