Description

Eicosanoic-20,20,20-D3 Acid is a high-purity, isotopically labeled derivative of arachidic acid, specifically deuterated at the terminal methyl group. This compound is essential as a stable isotope-labeled internal standard for precise quantitative analysis in mass spectrometry-based applications. It is primarily required by analytical laboratories and research institutions in the pharmaceutical, metabolomics, and lipid biochemistry sectors for method development and validation.

Application

• Mass Spectrometry Internal Standard: Serves as a critical reference compound for the accurate quantification of endogenous arachidic acid and related long-chain fatty acids in complex biological matrices like plasma, serum, and tissue samples.
• Metabolomics & Lipidomics Research: Enables precise tracking and measurement of fatty acid metabolism, absorption, and turnover in research studies investigating metabolic disorders, nutrition, and disease biomarkers.
• Pharmaceutical Development: Used in pharmacokinetic (PK) and pharmacodynamic (PD) studies to monitor drug effects on lipid pathways and ensure analytical method accuracy for regulatory submissions.
• Stable Isotope Tracer Studies: Acts as a tracer in clinical and preclinical research to elucidate the biochemical pathways and flux rates of saturated fatty acids.
• Quality Control & Method Validation: Provides a definitive standard for calibrating analytical instruments and validating LC-MS/MS methods in contract research organizations (CROs) and quality control labs.
