Quality Control

Our 1,2,3,3-Tetramethylbenz[E]Indolium Iodide is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed to confirm identity, potency, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing specifications such as purity (by HPLC), residual solvents, and heavy metals is provided with every shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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 degradation from atmospheric moisture.
