    摘要: The present invention relates to a 5-formylcytosine specific chemical labeling method and related applications in aspects such as sequencing, detection, imaging, and diagnosis. In the method, a condensation reaction occurs between an active methylene group in an active methylene compound containing a side-chain reactive group and an aldehyde group in 5-formylcytosine or a 1-substituted derivative of 5-formylcytosine, and at the same time an intramolecular reaction occurs between the side-chain reactive group of the active methylene compound and a 4-amino group of cytosine to implement ring closing. By means of the 5-formylcytosine specific chemical labeling method and related compounds of the present invention, detection of the content of 5-formylcytosine in nucleic acid molecules, and specific concentration of 5-formylcytosine-containing nucleic acid samples, and analysis of sequence distribution information of 5-formylcytosine and/or single-base resolution sequence information in nucleic acid molecules and the like may be implemented. The present invention provides various effective research methods in the research fields of epigenetics and nucleic acid biochemistry.
