Description

Naphthalene--D7 CAS NO 887-68-3 is a deuterated analog of naphthalene, where seven hydrogen atoms are replaced with deuterium atoms. This isotopic labeling is critical for providing an internal standard in mass spectrometry and NMR spectroscopy, ensuring unparalleled accuracy in quantitative analysis. It is an essential reagent for researchers and quality control laboratories in the pharmaceutical, agrochemical, and environmental testing industries who require high-fidelity analytical results.

Application

• Internal standard for the quantitative analysis of naphthalene and related polycyclic aromatic hydrocarbons (PAHs) via Gas Chromatography-Mass Spectrometry (GC-MS) or Liquid Chromatography-Mass Spectrometry (LC-MS).
• Deuterated tracer in metabolic and pharmacokinetic studies within pharmaceutical research and development.
• Critical component in environmental monitoring for the precise detection and quantification of naphthalene contaminants in soil, water, and air samples.
• NMR spectroscopy solvent and shift reference, particularly useful for structural elucidation and reaction mechanism studies in organic chemistry.
• Use in the synthesis of other deuterium-labeled compounds for advanced material science and mechanistic investigations.
• Quality control and method validation in analytical laboratories to comply with stringent regulatory standards (e.g., FDA, EPA).
