Quality Control

Our production of this reactive dye intermediate adheres to stringent quality protocols to ensure batch-to-batch consistency and purity. Products undergo rigorous analytical testing, including HPLC for assay and impurity profiling. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and relevant specifications is provided with each shipment to support your quality assurance and regulatory compliance needs.

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 tightly sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials.
