Quality Control

Our production of this azo dye intermediate adheres to strict quality management protocols to ensure batch-to-batch consistency and purity. Every lot is analyzed using advanced techniques including HPLC and spectrophotometry to verify identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and physical specifications is provided with each shipment to support your quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption and degradation. Keep away from incompatible materials.
