Quality Control

Our [2-[Ethyl[4-[(3-Phenyl-1,2,4-Thiadiazol-5-Yl)Azo]Phenyl]Amino]Ethyl]Trimethylammonium Dihydrogen Phosphate is produced under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure consistent quality and batch-to-batch reproducibility. Certificates of Analysis (COA) detailing all specifications are provided and available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
