Quality Control

Every batch of our azo dye intermediate is produced under a stringent quality management system. We guarantee consistent purity, chemical structure, and performance through advanced analytical techniques including HPLC, FT-IR, and elemental analysis. A comprehensive Certificate of Analysis (COA) detailing identity, assay, impurity profile, and physical specifications is provided with each shipment to ensure full traceability and compliance with your internal quality standards.

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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance and handling.
