Quality Control

Our production of 2-[4,4-Bis[4-(Dimethylamino)Phenyl]Buta-1,3-Dienyl]-1,3,3-Trimethyl-3H-Indolium Chloride adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets precise customer specifications and research-grade standards. A detailed Certificate of Analysis (COA) is provided with each shipment to guarantee traceability and consistency.

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 sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
