Pyrimidine yog cov tshuaj tsw qab heterocyclic organic zoo ib yam li pyridine. Ib ntawm peb diazines (rau-sib koom heterocyclics nrog ob lub nitrogen atoms hauv lub nplhaib), nws muaj nitrogen atoms ntawm txoj haujlwm 1 thiab 3 hauv lub nplhaib.:250 Lwm diazines yog pyrazine (nitrogen atoms ntawm 1 thiab 4 txoj haujlwm) thiab pyridazine (nitrogen atoms ntawm 1 thiab 2 txoj haujlwm). Hauv nucleic acids, peb hom nucleobases yog pyrimidine derivatives: cytosine (C), thymine (T), thiab uracil (U).
