3,3′-Diethylthiacarbocyanine iodide

Description:
3,3′-Diethylthiacarbocyanine iodide is a synthetic organic compound commonly used as a fluorescent dye in various biological and chemical applications. It belongs to the class of cyanine dyes, characterized by their extended conjugated systems, which contribute to their strong absorption and fluorescence properties. This compound typically exhibits a deep red to near-infrared color, making it useful for applications in microscopy and imaging techniques. Its structure includes a thiacarbocyanine backbone, which enhances its stability and photophysical properties. The iodide counterion is often included to balance the charge and improve solubility in various solvents. Due to its high molar absorptivity and fluorescence quantum yield, 3,3′-Diethylthiacarbocyanine iodide is frequently employed in labeling biomolecules, such as proteins and nucleic acids, facilitating the study of cellular processes. However, as with many synthetic dyes, it is essential to handle this compound with care, considering potential toxicity and environmental impact.
