The anti-epileptic agent remacemide hydrochloride has been prepared labelled with 14C, from [carbonyl-14C]acetophenone, and with 13C from [13C6]benzene, [1,2-13C]acetyl chloride and [1-13C]glycine. [2-3H]Glycine was utilised to prepare remacemide labelled with tritium at low specific activity. In addition other 2H- and high specific activity 3H-isotopomers of the drug, and of an active metabolite of
