## Abstract ^13^C‐, ^14^C‐ and ^15^N‐labelled ethylenethiourea was synthesized for NMR and radiotracer applications in metabolism and environmental fate studies. The products contained stable isotopes at 99% enrichment and the radiolabelled product had specific activity of 2.0 mCi/mmole.

Abstract
[^13^C‐carboxyl]Salicylic acid has been prepared by carbonation of 2‐benzyloxybromobenzene followed by reductive debenzylation. Deuterium and tritium labelled salicylic acid and ^2^H~2~/^13^C‐salicylic acid were prepared by reduction of the 3,5‐dibromo derivatives using Raney Ni‐Al. Deuterium labelled salicylic acid containing up to four deuterium atoms was prepared by catalytic exchange with Raney Ni‐Al in 5% NaOD/D~2~O.
