Quality Control

Our production of 2-[[4-[Ethyl[2-(Trimethylammonio)Ethyl]Amino]Phenyl]Azo]-6-Methoxy-3-Methylbenzothiazolium Bis(Methylsulphate) adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for color strength and chemical composition. Certificates of Analysis (COA) documenting all critical quality attributes 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 tightly sealed after use to prevent degradation from atmospheric moisture.
