Quality Control

Our 3-[[4-(Diethylamino)-o-Tolyl]Azo]-1,2-Dimethyl-5-Nitro-1H-Indazolium Chloride is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications. Certificates of Analysis (COA) documenting all critical parameters are provided with every shipment.

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.
