Description

1-Methylnaphthalene-D10 is a deuterated analog of 1-methylnaphthalene, where ten hydrogen atoms are replaced with deuterium. This high-purity isotopically labeled compound is essential as an internal standard for precise quantitative analysis in mass spectrometry and nuclear magnetic resonance (NMR) spectroscopy. It is a critical material for researchers and quality control laboratories in the pharmaceutical, environmental, and petrochemical industries, enabling accurate tracking and measurement of its non-deuterated counterpart in complex matrices.

Application

• Internal Standard for GC/MS and LC/MS: Used for the accurate quantification of 1-methylnaphthalene and related polycyclic aromatic hydrocarbons (PAHs) in environmental, food, and biological samples.
• NMR Spectroscopy Solvent & Tracer: Serves as a deuterated solvent or a chemical shift reference in NMR studies due to its distinct spectral properties.
• Metabolic and Pharmacokinetic Studies: Employed as a stable isotope-labeled tracer to study the absorption, distribution, metabolism, and excretion (ADME) of methylnaphthalenes in biological systems.
• Petroleum and Fuel Research: Acts as a diagnostic tool in the analysis of fuel composition, combustion byproducts, and lubricant degradation.
• Organic Synthesis Intermediate: Used in the synthesis of more complex deuterated compounds for specialized research applications.
• Quality Assurance & Method Development: Critical for developing and validating analytical methods in regulatory and industrial QC labs to ensure accuracy and reproducibility.
