Quality Control

Our production of 2-[[4-[Ethyl(2-Hydroxyethyl)Amino]Phenyl]Azo]-6-Methoxy-3-Methylbenzothiazolium Thiocyanate adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC for purity and spectrophotometry for color strength, to ensure consistent performance and compliance with customer specifications. Comprehensive Certificates of Analysis (COA) documenting identity, purity, and physical properties are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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.
