Description

1,2-Dimethoxybenzene-4,5-D2 CAS NO 203645-56-1 is a deuterated derivative of veratrole, where two hydrogen atoms are specifically replaced with deuterium, serving as a stable isotope-labeled compound. This deuteration is critical for enhancing analytical precision in spectroscopic and mass spectrometric studies by reducing signal interference. It is an essential building block and internal standard for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require high-fidelity isotopic tracers.

Application

• Pharmaceutical Research & Development: Used as a stable isotope-labeled internal standard in Liquid Chromatography-Mass Spectrometry (LC-MS) and Gas Chromatography-Mass Spectrometry (GC-MS) for the accurate quantification of drug metabolites and pharmacokinetic studies.
• Agrochemical Analysis: Employed in environmental fate studies and residue analysis of pesticides and herbicides, where deuterated analogs improve method accuracy and reliability.
• Organic Synthesis Intermediate: Acts as a specialized precursor for synthesizing more complex deuterated compounds, leveraging the dimethoxybenzene scaffold for further functionalization.
• NMR Spectroscopy Solvent & Reagent: Utilized in Nuclear Magnetic Resonance (NMR) spectroscopy as a probe or shift reagent, where deuterium incorporation provides distinct spectral signatures.
• Material Science Research: Serves in the development of deuterated polymers or liquid crystals, where isotopic substitution can fine-tune physical properties and stability.
• Metabolomics and Proteomics: Functions as a critical tool in quantitative metabolomics for tracing biochemical pathways and ensuring data integrity in complex biological samples.
