Abstract: Provided are any one of the following fluorescent compounds and a fluorescent labeled biological substance having this fluorescent compound.
X represents CR5 or N, and R1 to R7, Q1, Q2, L1, and L2 each represent a specific group.
a ring β1 and a ring β2 are a 5- to 8-membered ring,
At least one of R1 to R7, L1, L2, Q1, or Q2 has a specific hydrophilic group.
However, in a case where the ring β1 and the ring β2 are a 6-membered ring, and L1 and L2 are an arylene group, R5 is not an aryl group substituted with a linear alkyl group having 18 or more carbon atoms. In addition to the regulation of the ring β1, the ring β2, L1, and L2, in a case where R5 has a substituent having a dipyrromethene boron complex structure, the dipyrromethene boron complex structure has a structure in which a dipyrromethene skeleton is coordinately bonded to a boron atom in the tridentate or tetradentate coordination.-
