N3-Methylthymidine | CAS 958-74-7 | Powder, Purity ≥98.0% | EU Seller

N3-Methylthymidine (also known as 3-Methylthymidine) is a high-purity methylated nucleoside utilized as a reference standard for LC-MS/HPLC profiling and method development. In biochemical research, it serves as a critical tool for investigating nucleic acid modifications and the in vitro inhibition of DNA synthesis, specifically through the disruption of standard base-pairing capacity.
