Quality Control

Our 5-Hydroxy-1,2,3,3-Tetramethyl-3H-Indolium Iodide is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and FTIR, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with each shipment, confirming compliance with agreed specifications. Custom synthesis and purity grades (e.g., >98%, >99%) are available to meet specific project requirements.

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. Keep away from incompatible materials.
