Quality Control

Our production of this reactive dye intermediate adheres to strict quality management protocols to ensure batch-to-batch consistency and high chemical purity. Quality is verified through comprehensive analytical testing including HPLC, spectrophotometry, and titration methods. A Certificate of Analysis (COA) detailing purity, identity, and key impurity profiles is provided with each 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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance.
