Used as a deuterated internal standard in mass spectrometry for quantifying glycerol ether lipids in biological samples. Its stable isotopic label allows for accurate tracking and measurement in metabolic studies, particularly in lipidomics research. Also employed in the development and validation of analytical methods for lipid biomarkers in serum, plasma, and tissue extracts. The deuterated form ensures minimal interference with endogenous compounds while providing consistent chromatographic behavior and ionization efficiency.
