Description

2-Methoxy-D3-Pyrazine is a deuterated isotopologue of 2-methoxypyrazine, a key aromatic compound characterized by its methoxy-substituted pyrazine ring. This deuterated form is specifically engineered to provide enhanced stability and unique spectral properties for advanced research and analytical applications. It is an essential building block and reference standard for flavor and fragrance chemists, analytical laboratories, and pharmaceutical researchers working on metabolic studies, tracer analysis, and sophisticated aroma profiling.

Application

• Flavor and Fragrance Reference Standard: Serves as a critical internal standard and stable isotope-labeled reference in Gas Chromatography-Mass Spectrometry (GC-MS) for the precise quantification of methoxypyrazines in wines, coffee, and other food products.
• Metabolic Pathway Tracing: Used in pharmaceutical and biochemical research as a deuterium-labeled tracer to study metabolic pathways, degradation mechanisms, and the bioavailability of pyrazine derivatives.
• Aroma Compound Synthesis: Acts as a key deuterated intermediate in the synthesis of complex, labeled aroma molecules for research into flavor release and stability.
• Analytical Method Development: Essential for developing and validating highly sensitive and specific analytical methods (e.g., LC-MS/MS) in quality control laboratories for the flavor and fragrance industry.
• NMR Spectroscopy Studies: Utilized in Nuclear Magnetic Resonance (NMR) spectroscopy as a tool to simplify spectra and investigate molecular structures and interactions due to the distinct properties of deuterium.
