Description

2-Methoxy-D3-Ethanol CAS NO 97840-77-2 is a deuterium-labeled analog of 2-methoxyethanol, where three hydrogen atoms are replaced by the stable isotope deuterium (D). This isotopic labeling makes it an invaluable internal standard and tracer in quantitative analytical chemistry, particularly for mass spectrometry (MS) and nuclear magnetic resonance (NMR) studies. It is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and material science industries for metabolic pathway analysis, drug quantification, and the development of deuterated compounds.

Application

• Internal Standard for Mass Spectrometry (MS): Essential for accurate quantification of 2-methoxyethanol and its metabolites in biological and environmental samples via GC-MS or LC-MS.
• NMR Spectroscopy Solvent & Tracer: Serves as a deuterated solvent or a probe for studying molecular structures and reaction mechanisms without signal interference from protons.
• Pharmaceutical Research & Development: Used in pharmacokinetic and metabolic studies to track the fate of drug molecules and ensure regulatory compliance in bioanalysis.
• Deuterated Compound Synthesis: Acts as a key building block for synthesizing more complex deuterium-labeled fine chemicals and active pharmaceutical ingredients (APIs).
• Environmental and Forensic Analysis: Enables precise detection and measurement of trace levels of glycol ethers in complex matrices.
• Quality Control & Method Validation: Critical for developing and validating robust analytical methods in industrial and contract research laboratories.
