Quality Control

Our 2-[4-(Acetylphenylamino)Buta-1,3-Dienyl]-3-Ethylbenzoxazolium Iodide is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets exacting research and industrial standards. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed in a desiccated environment to prevent degradation. Keep away from incompatible materials.
