Quality Control

Our production of Bis[1-Benzyl-5-[[4-(Diethylamino)Phenyl]Azo]-2-(2-Hydroxyethyl)-1H-Pyrazolium] Tetrachlorozincate adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing to ensure consistent purity, color strength, and chemical identity. A detailed Certificate of Analysis (COA) documenting assay, impurity profile, and physical specifications is provided with each shipment to guarantee compliance with your technical requirements.

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 tightly sealed after each use to prevent degradation from atmospheric moisture.
