- Sulfo - Cy3 carboxylic acid fluorescent dye and preparation process thereof
-
The invention relates to a sulfo - Cy3 carboxylic acid fluorescent dye and a preparation process thereof, wherein the synthesized sulfo - Cy3 carboxylic acid has fluorescent quantum yield. At the same time, the high-emission high-excitation wavelength and is easily dissolved in water physical and chemical property stability points, and simultaneously, a single condensation target product needs to be selectively generated when the indole α-position methyl activity is achieved through simultaneous construction of the benzylindole two-side branch chains and high in yield, and C18 column separation is avoided.
