Also known as 5-methylpyrimidine-2,4(1H,3H)-dione, 2,4-dihydroxy-5-methylpyrimidine, 5-methyl-2,4(1H,3H)-pyrimidinedione, 5-methyluracil, Thymin, 2,4(1H,3H)-Pyrimidinedione, 5-methyl-, 5-Methyl-2,4-dihydroxypyrimidine, 5-Methyl-1,2,3,4-tetrahydropyrimidine-2,4-dione

Thymine () (symbol T or Thy) is one of the four nucleotide bases in the nucleic acid of DNA that are represented by the letters G–C–A–T. The others are adenine, guanine, and cytosine. Thymine is also known as 5-methyluracil, a pyrimidine nucleobase. In RNA, thymine is replaced by the nucleobase uracil. Thymine was first isolated in 1893 by Albrecht Kossel and Albert Neumann from calf thymus glands, hence its name.
