Guaifenesin-d3 (Guaiacol glyceryl ether-d3) is the deuterium labeled Guaifenesin. Guaifenesin (Guaiacol glyceryl ether), a constituent of guaiac resin from the wood ofGuajacum officinale Linné, is an expectorant. Guaifenesin can alleviate cough discomfortby increasing sputum volume and decreasing its viscosity, thereby promoting effective cough^[1][2].

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].
