Quality Control

Our tetrasodium reactive dye intermediate is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity, color strength, and chemical composition, meeting the exacting standards required for high-performance dye synthesis. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical specifications is provided with each shipment to guarantee traceability and compliance.

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