CAS 65-71-4

Thymine

Description:

Thymine, also known as 5-methyluracil, is one of the four nucleobases in the nucleic acid of DNA, playing a crucial role in the storage and transmission of genetic information. Its chemical formula is C5H6N2O2, and it features a pyrimidine ring structure, which is characterized by a six-membered ring containing two nitrogen atoms. Thymine is a white crystalline solid that is soluble in water and exhibits a melting point that varies depending on the specific conditions. It pairs with adenine through two hydrogen bonds in the DNA double helix, contributing to the stability of the genetic structure. Thymine is also involved in various biochemical processes, including DNA replication and repair. In addition to its biological significance, thymine can be synthesized in the laboratory and is used in various research applications, including studies on nucleic acids and genetic engineering. Its CAS number, 65-71-4, is a unique identifier that facilitates the identification and regulation of this compound in scientific literature and databases.
