Description

Ethanol-2-D1 is a deuterium-labeled isotopologue of ethanol, specifically deuterated at the 2-position (CAS NO 6181-08-4). This compound serves as a critical stable isotope-labeled internal standard, providing unmatched precision and reliability for quantitative analytical methods. It is essential for researchers and quality control laboratories in the pharmaceutical, metabolomics, and forensic toxicology sectors who require high-fidelity analytical standards for mass spectrometry and NMR spectroscopy.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a quantitative reference in GC-MS and LC-MS analyses of ethanol and related metabolites in biological matrices.
• Metabolic Pathway Tracing: Employed in metabolic flux analysis and pharmacokinetic studies to track the fate of ethanol in biological systems.
• NMR Spectroscopy Solvent & Standard: Acts as a deuterated solvent or chemical shift reference in nuclear magnetic resonance experiments.
• Pharmaceutical Impurity Profiling: Critical for the accurate quantification of residual solvents or process-related impurities in drug substances and products.
• Forensic and Clinical Toxicology: Ensures accurate blood alcohol content (BAC) measurements and studies of alcohol metabolism.
• Chemical Synthesis Intermediate: Serves as a labeled building block for the synthesis of more complex deuterated compounds.
