Tetrahydro-2H-pyran-2-one-d₄  (Synonyms: δ-valerolactone-d₄)

Tetrahydro-2H-pyran-2-one-d₄ is the deuterium labeled Tetrahydro-2H-pyran-2-one. Tetrahydro-2H-pyran-2-one is an endogenous metabolite with antioxidant capacity. Tetrahydro-2H-pyran-2-one is the small active molecule and can be used as drug intermediate^[1].

1. This compound can be used as a tracer.
2. This compound can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.

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].
