Uracil readily undergoes regular reactions including [[oxidation]], [[nitration]], and [[alkylation]]. While in the presence of [[phenol]] (PhOH) and [[sodium hypochlorite]] (NaOCl), uracil can be visualized in [[ultraviolet light]].<ref name="brown1">{{cite book|url=https://books.google.com/books?id=YpohAQAAMAAJ&q=malic+uracil|title=The Pyrimidines|vauthors=Brown DJ, Evans RF, Cowden WB, Fenn MD|publisher=Wiley|year=1994|isbn=9780471506560|veditors=Taylor EC|series=Heterocyclic Compounds|volume=52|location=New York, NY|archive-url=https://web.archive.org/web/20180512002431/https://books.google.com/books?id=YpohAQAAMAAJ&focus=searchwithinvolume&q=malic+uracil|archive-date=12 May 2018|url-status=live}}</ref> Uracil also has the capability to react with elemental [[halogen]]s because of the presence of more than one strongly electron donating group.<ref name="brown1"/>

Uracil readily undergoes addition to [[ribose]] [[sugar]]s and [[phosphate]]s to partake in synthesis and further reactions in the body.  Uracil becomes [[uridine]], [[uridine monophosphate]] (UMP), [[uridine diphosphate]] (UDP), [[uridine triphosphate]] (UTP), and [[uridine diphosphate glucose]] (UDP-glucose). Each one of these molecules is synthesized in the body and has specific functions.

When uracil reacts with anhydrous [[hydrazine]], a first-order kinetic reaction occurs and the uracil ring opens up.<ref name="Kochetkov1"/> If the [[pH]] of the reaction increases to >&nbsp;10.5, the uracil anion forms, making the reaction go much more slowly. The same slowing of the reaction occurs if the pH decreases, because of the protonation of the hydrazine.<ref name="Kochetkov1"/> The reactivity of uracil remains unchanged, even if the temperature changes.<ref name="Kochetkov1">{{cite book |title=Organic Chemistry of Nucleic Acids |publisher=Plenum Press |year=1972 |isbn=9781468429756 |volume=Part B |location=New York |doi=10.1007/978-1-4684-2973-2| veditors = Kochetkov NK, Budovskii EI }}</ref>
