Quality Control

Our production of 3-(3-Amino-3-Oxopropyl)-2-[[1-Methyl-2-(p-Tolyl)-1H-Indol-3-Yl]Azo]Benzothiazolium Chloride adheres to a stringent quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, spectrophotometric analysis for color value, and tests for residual solvents and moisture content. Certificates of Analysis (COA) detailing all specifications are provided with each shipment to ensure traceability and compliance with your internal quality 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 nature, the container must be kept sealed to prevent moisture absorption, which can affect product stability and performance. Keep away from incompatible materials.
