Used primarily in lipidomics and sphingolipid research, this compound serves as a stable isotope-labeled internal standard for the quantification and analysis of sphingolipid metabolism. It aids in studying enzymatic pathways, particularly those involving sphinganine and its derivatives, which are crucial in understanding cellular processes like apoptosis, proliferation, and signal transduction. Its application extends to investigating metabolic disorders and diseases linked to sphingolipid dysregulation, such as cancer, diabetes, and neurodegenerative conditions. Additionally, it is utilized in mass spectrometry-based assays to ensure accurate and reproducible measurements of sphingolipid levels in biological samples.
