## Abstract The synthesis of [2‐^3^H~2~]‐2‐aminoethanesulfonate [2‐^3^H]‐taurine by the reduction of cyanomethanesulfonic acid with tritium gas is described. The conversion of [2‐^3^H]‐taurine and its ^14^C and ^35^S isotopic forms to 2‐aminoethanesulfinate (hypotaurine) was accomplished by convert
