PROBLEM TO BE SOLVED: To provide a heterocyclic derivative containing a detectable segment. SOLUTION: This nucleic acid labeling compound has structure of the Chemical formula 3, wherein A represents H or a functional group for coupling the nucleic acid labeling compound to a nucleic acid, X represents O, S, NR<SB>1</SB>or CHR<SB>2</SB>, where R<SB>1</SB>and R<SB>2</SB>are independently H, alkyl or aryl, Y represents H, N<SB>3</SB>, F, OR<SB>9</SB>, SR<SB>9</SB>or NHR<SB>9</SB>, where R<SB>9</SB>is H, alkyl or aryl, Z represents H, N<SB>3</SB>, F, OR<SB>10</SB>, where R<SB>10</SB>is H, alkyl or aryl, L represents amino-alkyl, Q represents the detectable segment, and N represents a coupling group, where m is an integer within 0-about 3 of range.
