'''Carbon label''' is a form of [isotopic labeling](/source/isotopic_labeling) where a [carbon-12](/source/carbon-12) atom is replaced with either a stable [carbon-13](/source/carbon-13) atom or radioactive [carbon-11](/source/carbon-11) or [carbon-14](/source/carbon-14) atoms in a [chemical compound](/source/chemical_compound) so as to 'tag' (i.e. [label](/source/label)) that position of the compound to assist in determining the way a [chemical reaction](/source/chemical_reaction) proceeds i.e. the [reaction mechanism](/source/reaction_mechanism).<ref>{{cite journal |doi=10.1039/D1CC02665H |title=A general procedure for carbon isotope labeling of linear urea derivatives with carbon dioxide |date=2021 |last1=Babin |first1=Victor |last2=Sallustrau |first2=Antoine |last3=Loreau |first3=Olivier |last4=Caillé |first4=Fabien |last5=Goudet |first5=Amélie |last6=Cahuzac |first6=Héloïse |last7=Del Vecchio |first7=Antonio |last8=Taran |first8=Frédéric |last9=Audisio |first9=Davide |journal=Chemical Communications |volume=57 |issue=54 |pages=6680–6683 |pmid=34132265 |s2cid=235450623 }}</ref>
