Docosanoic acid-d₄-1（Cat No.:I044748）, also known as deuterated behenic acid, is a stable isotope-labeled long-chain saturated fatty acid containing four deuterium atoms. This 22-carbon fatty acid is used primarily as an internal standard in lipidomics and mass spectrometry for precise quantification and metabolic tracing. Its deuterium labeling allows differentiation from endogenous docosanoic acid in complex biological samples. Docosanoic acid-d₄-1 supports studies in fatty acid metabolism, membrane composition, and energy storage. It is also useful in research on lipid absorption, transport, and disorders involving altered fatty acid profiles.
