The present invention provides new intermediate compounds enabling the preparation of N-meso substituted cyanine, merocyanine or oxonole dyes wherein the N-meso substituent comprises electron withdrawing groups and wherein such N-meso substituents are introduced at the intermediate level. These intermediates enable the formation of dyes having in the meso-position N-substituents comprising electron withdrawing groups without the need for further derivatization of the meso-substituent at the dye level.

New indodicarbocyanine dyes with the carboxybutyl group in position-3 of the indolenine fragment bearing methyl and sulfonic groups in positions 5 and 7 of the cycle were synthesized in order to find the most effective fluorescent labels for the biological microchip technology. The position of absorption and fluorescence maxima, the total charge of the dye molecule, and water solubility depend on the location and the total amount of methyl and sulfonic groups. The spectral characteristics of the dyes synthesized were determined. The relative fluorescence efficiencies of the dyes at equal concentrations were measured at excitation wavelengths of 635 and 655 nm and emission wavelengths of 670 and 690 nm, respectively.
