Quality Control

Our production of this reactive dye intermediate adheres to strict quality management systems to ensure batch-to-batch consistency and high purity. Every lot is analyzed using advanced techniques like HPLC and spectrophotometry to confirm identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and physical specifications 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 nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product performance and stability.
