5-Chloro-2′-deoxycytidine (CAS 32387-56-7)

5-Chloro-2′-deoxycytidine is a modified nucleoside that is primarily used in the study of nucleic acid analogs and their incorporation into DNA. This compound is of particular interest in the field of molecular biology and genetics, where it is employed to understand the effects of halogenated nucleosides on DNA stability, replication, and repair mechanisms. As a cytidine analog, 5-Chloro-2′-deoxycytidine is useful in the synthesis of oligonucleotides with altered properties, which can be pivotal in studying protein-DNA interactions and the role of epigenetic modifications. Additionally, the chlorine substituent at the 5-position of the pyrimidine ring makes this compound a useful tool for probing the structural dynamics of DNA, as it can influence base-pairing and the overall conformation of the nucleic acid. Researchers also investigate the compound′s use in the labeling and detection of DNA, as it can provide insights into the localization and expression of specific genes.
