Quality Control

Our production of this reactive dye intermediate adheres to strict quality management systems to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing including HPLC, spectrophotometry, and titration methods. A detailed Certificate of Analysis (COA) specifying purity, identity, 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 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.
