Isocytosine Usage And Synthesis

Chemical Properties	White to Off-White Solid
Uses	Isocytosine is a useful intermediate for chemical modifications of base and sugar moieties in natural nucleosides
Uses	Isocytosine (2-aminouracil) is an isomer of cytosine used in physical chemical studies involving metal complex binding, hydrogen-bonding, and tautomerism and proton transfer effects in nucleobases.
Definition	ChEBI: An aminopyrimidine in which the pyrimidine ring bears amino and hydroxy substituents at positions 2 and 4, respectively.
