Quality Control

Our production of 2,2'-[Ethylenebis[Imino(3-Ethoxy-4,1-Phenylene)Azo]]Bis[3-Methylthiazolium] Sulphate adheres to stringent quality protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity, spectrophotometry for color strength, and elemental analysis. We provide a detailed Certificate of Analysis (COA) with each shipment, ensuring traceability and compliance with your specifications and relevant industry standards.

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 when not in use to prevent absorption of atmospheric moisture, which can affect product performance and stability.
