Quality Control

Our production of Bis[1,4-Dimethyl-5-[(2-Phenyl-1H-Indol-3-Yl)Azo]-1H-1,2,4-Triazolium] Sulphate adheres to stringent quality protocols to ensure batch-to-batch consistency and performance. Each lot undergoes comprehensive analytical testing, including assay, impurity profiling, and color strength evaluation. Certificates of Analysis (COA) documenting purity, identity, and key physical parameters 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 a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product performance and stability.
