Quality Control

Our 3-(4-((E)-2-[4-(Dibutylamino)Phenyl]Ethenyl)-1-Pyridiniumyl)-1-Propanesulfonate is produced under controlled conditions to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and loss on drying analysis. A comprehensive Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment to support your quality assurance and regulatory compliance needs.

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 tightly sealed after opening to prevent absorption of atmospheric moisture, which may affect product performance and stability.
