Used in lipid metabolism research to study the role of ceramides in cellular processes. It serves as an internal standard in mass spectrometry for accurate quantification of natural ceramides in biological samples. Applied in dermatology studies to understand skin barrier function and its implications in conditions like eczema or psoriasis. Also utilized in cancer research to investigate ceramide-mediated apoptosis and its potential therapeutic applications. Helps in tracking metabolic pathways and lipid signaling mechanisms in various diseases.
