Description

Octadecanoic-12-D1 Acid is a deuterium-labeled isotopologue of stearic acid, where a hydrogen atom at the 12-position is replaced by deuterium. This precise isotopic labeling makes it an indispensable internal standard and tracer in advanced analytical chemistry and metabolic research. It is primarily utilized by researchers and manufacturers in the pharmaceutical, biotechnology, and analytical chemistry sectors for applications requiring high isotopic purity and stability.

Application

• Internal Standard for Mass Spectrometry (MS): Used for the accurate quantification of stearic acid and related fatty acids in complex biological matrices via GC-MS or LC-MS.
• Metabolic Pathway Tracing: Serves as a stable, non-radioactive tracer to study lipid metabolism, absorption, and β-oxidation in biochemical and pharmacological research.
• Pharmaceutical Development: Employed in the research and quality control of lipid-based drug formulations and active pharmaceutical ingredients (APIs).
• NMR Spectroscopy: Acts as a useful probe in nuclear magnetic resonance studies due to the distinct signal of the deuterium atom.
• Biomarker Research: Facilitates the discovery and validation of lipid-based biomarkers in clinical and diagnostic studies.
• Chemical Synthesis: Used as a building block for synthesizing other deuterium-labeled compounds for research purposes.
