Description

Naphthalene-D8 CAS NO 1146-65-2 is a deuterated isotopologue of naphthalene, where all eight hydrogen atoms are replaced with deuterium. This high isotopic purity makes it an indispensable internal standard and tracer in quantitative analytical chemistry, particularly for mass spectrometry and NMR spectroscopy. It is essential for researchers and quality control laboratories in the pharmaceutical, environmental, and advanced materials sectors who require precise, interference-free measurements.

Application

• Internal Standard for GC-MS & LC-MS: Used for the accurate quantification of naphthalene and related polycyclic aromatic hydrocarbons (PAHs) in environmental, food, and biological samples.
• NMR Spectroscopy Solvent & Shift Reference: Serves as a deuterated solvent or chemical shift reference in nuclear magnetic resonance studies.
• Metabolic & Pharmacokinetic Tracer: Employed in drug metabolism and disposition studies to track the fate of naphthalene-based compounds.
• Polymer & Materials Science Research: Acts as a probe in mechanistic studies of polymerization and degradation processes.
• Environmental Fate Studies: Tracks the degradation, transformation, and transport of naphthalene in complex environmental systems.
• Analytical Method Development & Validation: Critical for developing and validating robust, high-precision analytical protocols in regulatory and R&D settings.
