CAS 71-30-7
:Cytosine
Description:
Cytosine is a pyrimidine nucleobase that plays a crucial role in the genetic coding of organisms. It is one of the four primary bases found in DNA and RNA, pairing with guanine in DNA and RNA structures. The chemical formula of cytosine is C4H5N3O, and it has a molecular weight of approximately 111.13 g/mol. Cytosine is characterized by its aromatic ring structure, which includes two nitrogen atoms and one carbonyl group, contributing to its ability to form hydrogen bonds with complementary bases. It is a white crystalline solid at room temperature and is soluble in water, which facilitates its biological functions. Cytosine can undergo various chemical modifications, such as methylation, which can influence gene expression and cellular processes. In addition to its biological significance, cytosine is also involved in various biochemical pathways and can be synthesized in the laboratory for research purposes. Its CAS number, 71-30-7, is a unique identifier used for regulatory and commercial purposes.
