Description

Stearic Acid-9,10-D2 is a deuterium-labeled analog of stearic acid, a saturated long-chain fatty acid, where two hydrogen atoms at the 9 and 10 positions are replaced with deuterium (D). This isotopic labeling makes it an invaluable internal standard and tracer in mass spectrometry and metabolic research, providing unmatched accuracy for quantitative analysis. It is primarily required by analytical laboratories, pharmaceutical R&D departments, and academic institutions engaged in lipidomics, stable isotope probing, and pharmacokinetic studies.

Application

• Internal standard for the precise quantification of stearic acid and related lipids in biological matrices via GC-MS or LC-MS.
• Tracer molecule in metabolic flux analysis and lipid metabolism studies to track biochemical pathways.
• Critical reagent in the development and validation of analytical methods for fatty acid profiling in food, clinical, and environmental testing.
• Used in pharmaceutical research for drug metabolism and pharmacokinetic (DMPK) studies involving lipid-based formulations.
• Component in the synthesis of other deuterium-labeled compounds for advanced research applications.
• Reference material for calibrating spectroscopic and chromatographic instruments in quality control laboratories.
