Product Description

 CAS 71-30-7 Cytosine  (C4H5N3O)
 
   Cytosine is one of the four nucleobases found in DNA and RNA, along with adenine, guanine, and thymine. It is a pyrimidine derivative, with a heterocyclic aromatic ring and two substituents attached. The nucleoside of cytosine is cytidine. In Watson-Crick base pairing, it forms three hydrogen bonds with guanine.

   Cytosine reagent is used in a wide variety of research applications, as an enzyme substrate or precursor of effector molecules such as cytosine sugars.   Cytosine is the raw materials for the production of Molnupiravir
