Description

Methyl Hexadecanoate-D31 CAS NO 29848-79-1 is a stable isotope-labeled analog of methyl palmitate, where all hydrogen atoms are replaced by deuterium. This high-purity compound is essential for applications requiring precise internal standards and tracer studies, ensuring accurate quantification and minimizing analytical interference. It is primarily utilized by researchers and quality control laboratories in the pharmaceutical, analytical chemistry, and metabolic research sectors for advanced mass spectrometry and NMR spectroscopy.

Application

• Internal Standard for Mass Spectrometry (MS): Serves as a critical quantitative reference standard in GC-MS and LC-MS analyses of lipids and fatty acid esters.
• Metabolic Pathway Tracing: Used in deuterium-labeling studies to investigate lipid metabolism, biosynthesis, and degradation pathways in biological systems.
• NMR Spectroscopy Solvent & Reagent: Acts as a deuterated solvent or a probe molecule in nuclear magnetic resonance studies due to its lack of proton signals.
• Pharmaceutical Research & Development: Employed in the development and validation of analytical methods for drug substances and excipients containing fatty acid chains.
• Quality Control & Reference Material: Provides a certified reference material for calibrating instruments and verifying the accuracy of analytical methods in industrial QC labs.
• Chemical Synthesis Intermediate: Used as a specialized, labeled building block in the synthesis of more complex deuterated compounds for research.
