Quality Control

Our production of 2-[[4-Chloro-6-[[4-[(1-Hydroxy-4-Sulfo-2-Naphthalenyl)Azo]-3-Sulfophenyl]Amino]-1,3,5-Triazin-2-Yl]Amino]-1,4-Benzenedisulfonic Acid Tetrasodium Salt adheres to a stringent quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure consistent performance and batch-to-batch reliability for your synthesis processes. Certificates of Analysis (COA) detailing all specifications are provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 opening to prevent absorption of atmospheric moisture, which can affect product quality and handling.
