Quality Control

Our production of 2-[[4-(Dimethylamino)Phenyl]Azo]-1-Methylpyridinium Methyl Sulphate adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing to ensure high purity, consistent color strength, and precise chemical composition. Certificates of Analysis (COA) detailing purity, impurity profile, and physical specifications are provided with each shipment to guarantee traceability and compliance with your technical requirements.

Storage

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