Description

Decanoic-9,9,10,10,10-D5 Acid CAS NO 1219803-00-5 is a deuterium-labeled isotopologue of capric acid, where five hydrogen atoms at the terminal methyl group are replaced with deuterium. This high-purity stable isotope-labeled compound is critical for applications requiring precise internal standards in mass spectrometry and advanced metabolic research. It is primarily utilized by analytical chemists and researchers in the pharmaceutical, agrochemical, and life science industries for quantitative analysis and tracer studies.

Application

• Internal Standard for Mass Spectrometry (MS): Essential for accurate quantification of capric acid and related compounds in complex biological matrices like plasma, serum, and tissue samples.
• Metabolic Pathway Tracing: Used in stable isotope labeling studies to investigate lipid metabolism, fatty acid oxidation, and energy production pathways.
• Pharmaceutical Research & Development: Supports drug metabolism and pharmacokinetics (DMPK) studies for candidate drugs involving fatty acid pathways.
• Nutritional Science Research: Enables precise tracking of medium-chain fatty acid absorption, distribution, and utilization in dietary studies.
• Biomarker Discovery and Validation: Serves as a critical reference standard in the development of clinical assays for metabolic disorders.
• Chemical Synthesis Intermediate: Acts as a labeled building block for the synthesis of more complex deuterated molecules for research purposes.
• Environmental Analysis: Can be employed as a standard in the analysis of fatty acids in environmental samples.
