Description

n-Undecane-D24 is a fully deuterated isotopologue of the linear alkane undecane, where all 24 hydrogen atoms are replaced by deuterium (²H). This high isotopic purity makes it an essential internal standard and tracer in advanced analytical chemistry and materials science research. It is primarily used by researchers and quality control laboratories in the pharmaceutical, petrochemical, and environmental sectors for precise quantitative analysis using techniques like NMR spectroscopy and mass spectrometry.

Application

• Internal Standard for Mass Spectrometry (MS): Provides a stable, non-interfering reference peak for the accurate quantification of hydrocarbons and related compounds in complex matrices like fuels, oils, and environmental samples.
• NMR Spectroscopy Solvent & Tracer: Serves as an inert, deuterated solvent for NMR studies or as a specific tracer to elucidate reaction mechanisms and metabolic pathways without signal interference from protons.
• Pharmaceutical Research & Metabolism Studies: Used in drug development to track the absorption, distribution, metabolism, and excretion (ADME) of new chemical entities using isotope-labeling techniques.
• Polymer Science & Material Research: Acts as a probe or additive in the study of polymer dynamics, diffusion processes, and the microstructure of advanced materials.
• Petrochemical Analysis: Employed in the detailed characterization of crude oil fractions, lubricants, and synthetic fuels for precise component analysis.
• Environmental Science: Utilized as a standard in the analysis of hydrocarbon pollutants, enabling high-precision tracking and quantification in soil and water samples.

Quality Control

Every batch of n-Undecane-D24 is produced and analyzed under strict quality management protocols to ensure exceptional isotopic and chemical purity. Our products undergo rigorous testing, including NMR, GC-MS, and IR spectroscopy, to confirm identity and isotopic enrichment. A comprehensive Certificate of Analysis (COA) detailing batch-specific results for isotopic purity, chemical assay, and solvent residues is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Keep away from strong acids and oxidizing agents. For long-term storage under an inert atmosphere (e.g., argon or nitrogen), please contact us.
