Quality Control

Our Acid Red 54 is manufactured under a strict quality management system. Every batch is tested to confirm identity, purity, and performance characteristics against established specifications. While primarily supplied for industrial use, production can reference standards for color purity and heavy metal limits. A Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at ambient temperature (15-25°C). Keep away from strong oxidizing agents. Due to its light-sensitive nature, prolonged exposure to direct light should be avoided to maintain color stability.
