5-Chloro-2′-deoxyuridine (5-Cl-dUrd, CldU) is a halogenated uridine derivative employed in studying DNA and DNA precursor damage. It serves as a thymidine analogue and is readily incorporated into newly synthesized DNA in place of thymidine following phosphorylation. The presence of thymidine analogs, including CldU, can induce significant modifications in DNA processing and replication, making them useful as mutagens, clastogens, and antiviral agents in various applications.
