Quality Control

Our production of this azo dye intermediate adheres to stringent quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including HPLC and spectrophotometry to verify identity and assay. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory needs.

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 after opening to prevent degradation from atmospheric moisture.
