Quality Control

Our 1,5-Dimethyl-3-[(2-Methyl-1H-Indol-3-Yl)Azo]-2-Phenyl-1H-Pyrazolium Acetate is produced under strict quality management protocols. Every batch undergoes rigorous analytical testing to ensure high purity, consistent performance, and batch-to-batch reliability. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles 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 each use to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
