Description

1,5-Di(Methyl-D3)-Naphthalene is a deuterated organic compound where two methyl groups on the naphthalene core are specifically labeled with deuterium (D or ²H) atoms. This isotopic labeling is critical for applications requiring precise molecular tracking, structural elucidation, and minimizing background interference in analytical techniques. It serves as a vital building block and internal standard for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require high isotopic purity and chemical stability.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a quantitative reference standard in LC-MS and GC-MS analysis due to its nearly identical chemical properties but distinct mass.
• Pharmaceutical Research & Metabolism Studies: Employed as a stable isotope-labeled tracer to study drug metabolism, pharmacokinetics (ADME), and biochemical pathways.
• NMR Spectroscopy Solvent & Reagent: Acts as a deuterated solvent or a probe molecule in Nuclear Magnetic Resonance (NMR) spectroscopy for structural analysis.
• Organic Light-Emitting Diodes (OLEDs) Research: Serves as a deuterated precursor in the development of organic electronic materials to study and enhance device performance and longevity.
• Polymer & Material Science: Utilized in the synthesis of deuterated polymers for neutron scattering studies to investigate polymer dynamics and structure.
• Agrochemical Development: Applied in the research and environmental fate studies of pesticides and herbicides using isotope tracing methods.
