Thymidine is widely used in molecular biology as a DNA synthesis precursor, particularly in cell proliferation assays and thymidine incorporation studies. It serves as a critical component in cell culture media for maintaining nucleotide pools. Researchers also utilize radiolabeled Thymidine (e.g., [³H]-Thymidine) to track DNA replication in vivo and in vitro. In pharmaceutical development, it’s employed as a standard reference material and as an impurity marker in antiretroviral drug analysis.
