<p>A compound represented by general formula [1] or a salt thereof, which is a novel cyanine dye derivative having a high fluorescence intensity in a short-wavelength region. The cyanine dye derivative has a structure comprising a pyrazole skeleton and an indole skeleton combined therewith through a polymethine chain, and has been rendered controllable with respect to electrophoretic mobility by further introducing a quaternary ammonium cation into a molecule having that structure. (In formula [1], R1 to R6 each independently represents, for example, an alkyl having a substituent represented by general formula [101], R7 to R10 each independently represents a hydrogen atom, etc., R11 represents a hydrogen atom, an alkyl, etc., and n is an integer of 0-3, at least one of R1 to R6 being an alkyl having a substituent represented by general formula [101].)</p> |
