Quality Control

Our 1,1'-Dipentyl-3,3,3',3'-Tetramethylindocarbocyanine Iodide is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity for research and industrial use. Each lot undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance protocols.

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 tightly sealed in a desiccated environment to prevent degradation. For long-term stability, consider storage under an inert atmosphere.
