Quality Control

Our production of this reactive dye intermediate adheres to strict quality management systems to ensure batch-to-batch consistency and purity. Every lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profile, spectrophotometry for color strength, and identification via FT-IR. We provide full traceability and Certificates of Analysis (COA) are available upon request 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 to prevent moisture absorption, which can affect product performance. Keep away from incompatible materials.
