Deuterium is less lipophilic than hydrogen, and this can result in the deuterated standard not co-eluting with the unlabeled compound. 3,4 Carbon-13 Label Labeling with 13C has none of the disadvantages of deuterium labeling. Carbon-13 can be obtained in

Hydrogen–deuterium exchange - Wikipedia

WebHydrogen–deuterium exchange (also called H–D or H/D exchange) is a chemical reaction in which a covalently bonded hydrogen atom is replaced by a deuterium atom, or vice versa. It can be applied most easily to exchangeable protons and deuterons, where such a transformation occurs in the presence of a suitable deuterium source, without any catalyst. citing the criminal code of canada
