Used in biochemical research as a modified amino acid analog, particularly in studies involving nucleotide metabolism and enzyme inhibition. Its structure combines features of amino acids and pyrimidine bases, making it useful for probing enzymatic pathways such as those involving deaminases or phosphorylases. Also employed in the synthesis of labeled peptides or nucleic acid derivatives for diagnostic or imaging applications, especially where iodine labeling is needed for detection or radiotracing. Shows potential in antiviral and anticancer agent development due to its ability to interfere with DNA/RNA synthesis pathways.
