Description

Dodecanoic-11,11,12,12,12-D5 Acid is a deuterium-labeled isotopologue of lauric acid, a medium-chain saturated fatty acid, where five hydrogen atoms are replaced with deuterium at specific positions. This high-purity stable isotope-labeled compound is essential for advanced analytical and research applications requiring precise internal standards and metabolic tracers. It is primarily utilized by analytical chemists, pharmaceutical researchers, and material scientists in fields such as mass spectrometry, NMR spectroscopy, and metabolic pathway studies.

Application

• Internal Standard for Mass Spectrometry (MS): Serves as a critical quantitative reference standard in GC-MS and LC-MS analyses for accurate measurement of lauric acid and related metabolites in complex biological and environmental matrices.
• Metabolic Research & Tracer Studies: Used as a stable isotope tracer to investigate lipid metabolism, fatty acid oxidation, and biosynthetic pathways in pharmacokinetic and biochemical research.
• NMR Spectroscopy Solvent & Reagent: Acts as a useful probe in deuterium NMR (²H NMR) studies due to its specific deuterium labeling pattern, aiding in structural elucidation and dynamic analysis.
• Pharmaceutical Development: Employed in the research and development of lipid-based drug delivery systems and in studying the behavior of fatty acid-conjugated active pharmaceutical ingredients (APIs).
• Chemical Synthesis Intermediate: Functions as a specialized building block for synthesizing deuterium-labeled surfactants, esters, and other fine chemicals where isotopic labeling is required.
• Quality Control & Method Development: Integral for developing and validating analytical methods in regulatory environments, food testing, and clinical diagnostics.
