Description

Pentadecanoic-15,15,15-D3 Acid is a high-purity, isotopically labeled analog of pentadecanoic acid, where three deuterium atoms replace the terminal methyl hydrogens. This stable isotope labeling is critical for applications requiring precise metabolic tracing and quantification without radioactive hazards. It is an essential tool for researchers and analytical scientists in pharmaceutical development, lipid metabolism studies, and clinical diagnostics.

Application

• Internal Standard for Mass Spectrometry: Used as a quantitative reference standard in GC-MS and LC-MS/MS analysis of fatty acids and complex lipids.
• Metabolic Pathway Tracing: Enables detailed investigation of fatty acid β-oxidation, biosynthesis, and incorporation into complex lipids in biological systems.
• Pharmaceutical Research: Serves as a tracer in drug metabolism and pharmacokinetics (DMPK) studies for candidate drugs targeting lipid pathways.
• Clinical Diagnostics: Employed in the development of assays for inborn errors of metabolism and other disorders related to fatty acid processing.
• Nutritional Science: Facilitates studies on dietary fat absorption, distribution, and metabolism in animal and human models.
• Biomarker Discovery & Validation: Aids in the accurate quantification of pentadecanoic acid and related metabolites as potential disease biomarkers.
