Quality Control

Our Trilithium-1-Hydroxy-7-(3-Sulfonatoanilino)-2-(3-Methyl-4-(2-Methoxy-4-(3-Sulfonatophenylazo)Phenylazo)Phenylazo)Naphthalene-3-Sulfonate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, color value, and chemical composition. Certificates of Analysis (COA) detailing key parameters such as assay, impurity profile, and heavy metal content are provided to guarantee compliance with your specific application requirements.

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 to prevent absorption of atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents.
