Quality Control

Our production of this dye intermediate adheres to strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via FT-IR and UV-Vis spectroscopy, to ensure consistency and meet customer specifications. Certificates of Analysis (COA) documenting all critical parameters are provided with each shipment and are available upon request.

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 handling properties.
