thymine riboside

The chemical compound thymine riboside (5-methyluridine, also called ribothymidine), is a pyrimidine nucleoside. It is the ribonucleoside counterpart to the deoxyribonucleoside thymidine, which lacks a hydroxyl group at the 2' position. 5-Methyluridine contains a thymine base joined to a ribose pentose sugar.

It exists in solid form as small white crystals or white crystalline powder, has a molecular weight of 258.23 u, and has a melting point of 185 °C. The stability of 5-methyluridine under standard temperature and pressure (STP) is very high.
