Quality Control

Our production of 2-[[4-[Ethyl(2-Hydroxyethyl)Amino]Phenyl]Azo]-6-Methoxy-3-Methylbenzothiazolium Acetate adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure compliance with industry specifications. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and physical properties is provided with each shipment to guarantee traceability and performance consistency.

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.
