1,1'-diethyl-3,3,3',3'-tetramethylindo-carbocyanine iodide

Description:
1,1'-Diethyl-3,3,3',3'-tetramethylindo-carbocyanine iodide, commonly referred to as DiI, is a synthetic dye belonging to the cyanine family. It is characterized by its vibrant red fluorescence, making it widely used in biological and biochemical applications, particularly in cell labeling and tracking studies. The compound exhibits high solubility in organic solvents and is relatively stable under physiological conditions, which enhances its utility in various experimental setups. DiI's fluorescence properties are sensitive to the environment, allowing researchers to study membrane dynamics and cellular interactions. The iodide counterion contributes to its solubility and stability. However, like many synthetic dyes, it may pose environmental and health risks, necessitating careful handling and disposal. Overall, DiI serves as a valuable tool in fluorescence microscopy and other imaging techniques, providing insights into cellular processes and structures.
