Near-IR heptamethine cyanine dyes were synthesized without substitution to the polyene chain but with various substituents on the indoleninium fragments. To develop indotricarbocyanine dyes with improved photochem. characteristics, we studied the relation between the structures of these compounds, their spectral properties, their photostability, and thermal stability. In the experiment, the researchers used many compounds, for example, 1-Ethyl-2,3,3-trimethyl-3H-indol-1-ium-5-sulfonate (cas: 146368-07-2Formula: C13H17NO3S).
1-Ethyl-2,3,3-trimethyl-3H-indol-1-ium-5-sulfonate (cas: 146368-07-2) belongs to indole derivatives. In addition to tryptophan, indigo, and indoleacetic acid, numerous compounds obtainable from plant or animal sources contain the indole molecular structure. They are capable of binding to a variety of receptors with high affinity and thus have applications in a wide range of therapeutic areas.Formula: C13H17NO3S
