5-Methyluridine, also known as ribothymidine (rT), is a modified pyrimidine RNA nucleoside with 5-methyluracil linked to β-D-ribose. CH64014 is identified by CAS 1463-10-1, molecular formula C10H14N2O6, molecular weight 258.23, and PubChem CID 445408. It is distinct from thymidine (CH64004), which contains 2-deoxyribose.
In tRNA literature, ribothymidine is the conserved modified nucleoside at position 54 of the TΨC loop. This supports its use as a reference residue in tRNA-modification and modified-RNA chemistry research.

常见问题
What is the difference between 5-methyluridine and thymidine?
5-Methyluridine (ribothymidine) is the RNA nucleoside — 5-methyluracil on ribose. Thymidine is the DNA nucleoside — the same base on 2-deoxyribose. They are cataloged separately.
Why is 5-methyluridine relevant to tRNA research?
As ribothymidine (rT), it is the conserved modified nucleoside at position 54 of the tRNA TΨC loop, so it is a reference residue in studies of tRNA modification.
