Description

(1,2,3,4-2H4)Naphthalene is a deuterium-labeled isotopologue of naphthalene, a fundamental polycyclic aromatic hydrocarbon. This high-purity stable isotope is critical for applications requiring precise internal standards and non-radioactive tracers in advanced analytical chemistry. It is primarily utilized by research institutions, analytical laboratories, and pharmaceutical developers engaged in mass spectrometry, metabolic studies, and environmental analysis.

Application

• Internal Standard for Mass Spectrometry (MS): Serves as a quantitative reference standard in GC-MS and LC-MS analysis for accurate quantification of native naphthalene and related compounds.
• Metabolic Pathway Tracing: Used in pharmaceutical and biochemical research to study the metabolism, distribution, and excretion of polycyclic aromatic compounds.
• Environmental Analysis: Enables precise tracking and quantification of naphthalene pollutants in complex environmental matrices like soil and water.
• NMR Spectroscopy Solvent & Reagent: Employed as a deuterated solvent shift reagent or a probe in nuclear magnetic resonance studies.
• Chemical Reaction Mechanism Studies: Acts as a tracer to elucidate kinetic isotope effects and detailed reaction pathways in organic synthesis.
• Quality Control & Method Validation: Essential for developing and validating robust analytical methods in regulatory and quality assurance laboratories.
