Description

Heptadecanoic-17,17,17-D3 Acid is a deuterium-labeled analog of margaric acid, a saturated 17-carbon fatty acid. This stable isotope-labeled compound is essential for use as an internal standard in quantitative mass spectrometry (MS) and gas chromatography-mass spectrometry (GC-MS) analysis, ensuring unparalleled accuracy in trace-level detection. It is critically needed by analytical laboratories, pharmaceutical researchers, and agrochemical developers for applications in lipidomics, metabolic studies, and pharmacokinetic research where precise quantification is non-negotiable.

Application

• Internal Standard for Mass Spectrometry: Primary application as a quantitative reference standard in LC-MS and GC-MS analysis of fatty acids and complex lipids.
• Biomedical & Pharmaceutical Research: Used in metabolic flux analysis, drug metabolism and pharmacokinetics (DMPK) studies, and biomarker discovery.
• Nutritional Science & Lipidomics: Enables accurate profiling and quantification of fatty acids in biological samples, food products, and dietary supplements.
• Agrochemical & Environmental Analysis: Serves as a stable isotope tracer in studies of lipid metabolism in plants or for detecting fatty acid-based compounds in environmental samples.
• Chemical Synthesis & Isotope Labeling: Acts as a labeled building block for the synthesis of more complex deuterated molecules for research purposes.
• Quality Control & Reference Material: Provides a certified reference material for calibrating analytical instruments and validating methods in QA/QC laboratories.
