Description

1,8-Dimethylnaphthalene-D12 is a deuterated analog of 1,8-dimethylnaphthalene, where all hydrogen atoms have been replaced with deuterium (D), a stable hydrogen isotope. This high isotopic purity makes it an essential internal standard and tracer in advanced analytical chemistry, particularly for mass spectrometry and NMR spectroscopy, ensuring precise quantification and eliminating interference from endogenous compounds. It is primarily utilized by researchers and quality control laboratories in the pharmaceutical, environmental analysis, and petrochemical industries for method development, metabolic studies, and complex mixture analysis.

Application

• Internal Standard for GC-MS and LC-MS: Used for the accurate quantification of 1,8-dimethylnaphthalene and related polycyclic aromatic hydrocarbons (PAHs) in complex matrices.
• NMR Spectroscopy Solvent & Tracer: Serves as a deuterated solvent shift reference or a non-interfering tracer in reaction mechanism studies.
• Pharmaceutical Research: Employed in drug metabolism and pharmacokinetics (DMPK) studies as a stable isotope-labeled analog for tracking and quantification.
• Environmental Analysis: Critical for monitoring and quantifying PAH pollutants in soil, water, and air samples with high precision.
• Petrochemical & Fuel Analysis: Used in the detailed characterization of hydrocarbon streams and the analysis of diesel and jet fuel components.
• Organic Synthesis Intermediate: Acts as a labeled building block for the synthesis of more complex deuterated compounds for research.
• Quality Control & Method Validation: Essential for developing and validating analytical methods in accredited laboratories to ensure accuracy and reproducibility.
