Description

n-Tetracosane-D50 is a deuterium-labeled isotopologue of the straight-chain hydrocarbon tetracosane, where 50 hydrogen atoms are replaced by deuterium (CAS NO 16416-32-3). This high isotopic purity makes it an indispensable internal standard and tracer in advanced analytical chemistry and metabolic research. It is primarily required by research institutions, pharmaceutical developers, and analytical laboratories engaged in quantitative mass spectrometry, nuclear magnetic resonance (NMR) spectroscopy, and kinetic studies.

Application

• Internal Standard for Mass Spectrometry (MS): Used for the precise quantification of lipids, hydrocarbons, and other long-chain compounds in GC-MS and LC-MS applications due to its near-identical chemical properties with distinct mass.
• Metabolic Pathway Tracer: Employed in biomedical and biochemical research to track and elucidate metabolic pathways and mechanisms in vivo and in vitro.
• NMR Spectroscopy Solvent & Reference: Serves as a deuterated solvent or chemical shift reference in NMR studies, particularly for analyzing hydrophobic compounds or matrices.
• Polymer Science Research: Acts as a probe or model compound in studies of polymer crystallization, diffusion, and phase behavior.
• Calibration Standard: Used to calibrate analytical instruments for the accurate detection and measurement of long-chain alkanes.
• Isotope Dilution Analysis: Critical for high-accuracy quantification in environmental analysis, petrochemistry, and quality control of complex mixtures.
