Quality Control

Every batch of our Disodium Hydrogen -2-[6-[(2,4-Dimethylsulphonatophenyl)Amino]-3-[(2,4-Dimethylsulphonatophenyl)Imino]-3H-Xanthen-9-Yl]Benzenesulphonate undergoes rigorous quality testing to ensure it meets stringent specifications for purity and performance. Our quality system is designed to guarantee batch-to-batch consistency, which is critical for sensitive analytical and diagnostic applications. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available upon request.

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 to prevent absorption of atmospheric moisture, which can affect product performance and stability.
