Hexadecanamide-13,13,14,14,15,15,16,16,16-d9, N-[(1S,2R)-2-hydroxy-1-(hydroxymethyl)heptadecyl]-

N-palmitoyl(d9) dihydrosphingosine CER10(d9) has been used as a deuterium-labeled ceramide internal standard in lipid extraction from human and mouse stratum corneum (SC) samples for liquid chromatography tandem-mass spectrometry (LC–MS/MS) analysis.

Dihydrosphingosine provides protection to the skin by acting as a lipid barrier.
