Propylparaben-d₄  (Synonyms: Propyl parahydroxybenzoate-d₄; Propyl 4-hydroxybenzoate-d₄)

Propylparaben-d₄ (Propyl parahydroxybenzoate-d4) is the deuterium labeled Propylparaben (HY-N2026). Propylparaben (Propyl parahydroxybenzoate) is an antibacterial preservative that can be produced by plants and bacteria. Propylparaben is an orally active weak estrogen receptor agonist. Propylparaben regulates the PI3K-AKT and JNK signaling pathways, and induces oxidative stress. Propylparaben is commonly used in cosmetics, pharmaceuticals and foods, and can be used in studies related to ovarian aging and myocardial ischemia-reperfusion injury^{[1][2][3][4][5]}.

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.
