Synthesis and stability of [1,3‐¹⁴C₂]‐glyceryl trinitrate

Abstract

SummaryThe synthesis of [1,3-14C2]-glyceryl trinitrate ( [k]-GTN) labelled with quasi carrier free carbon-14 atom in the 1,3-positions of the molecule was effected in four reaction steps from 14CO2 ( 3 3 % overall yield). The chemical and radiochemical purity of [14C]-GTN was found better than 99% controlled by HPLC-Radioactivity Monitor and TLC-Digital Autoradiograph methods. Study of the radiochemical stability in dilute solution at 5 OC shows that the product can be stored at least for a month without detectable decomposition.
