Stearoyl-L-carnitine-d₃ (chloride) is the deuterium labeled Stearoyl-L-carnitine chloride. Stearoyl-L-carnitine chloride is an endogenous long-chain acylcarnitine. Stearoyl-L-carnitine chloride is a less potent inhibitor of GlyT2. Stearoyl-L-carnitine chloride inhibits glycine responses by 16.8% at concentrations up 3 μM.

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.
