Used in research as a modified nucleoside for studying DNA structure and function. Acts as a building block in the synthesis of oligonucleotides with tailored properties, particularly in antisense technology and nucleic acid therapeutics. The anisoyl group enhances stability and can influence base pairing or hybridization behavior. Also explored in epigenetic studies due to its structural similarity to natural cytidine derivatives, enabling investigation of enzyme substrates involved in DNA methylation and repair.
