Description

Naphthalene-1,4-D2 CAS NO 1683-98-3 is a deuterated derivative of naphthalene, specifically labeled at the 1 and 4 positions. This isotopic labeling is critical for applications requiring non-radioactive tracers or internal standards in advanced analytical techniques. It is an essential material for researchers and developers in the fields of analytical chemistry, pharmaceuticals, and materials science who require high-purity, isotopically labeled compounds for precise measurements and mechanistic studies.

Application

• Internal Standard for Quantitative Analysis: Serves as a stable, non-radioactive internal standard in Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS) for accurate quantification of naphthalene and related compounds.
• Deuterated NMR Solvent & Shift Reference: Used as a chemical shift reference or as a component in deuterated solvent mixtures for Nuclear Magnetic Resonance (NMR) spectroscopy.
• Metabolic & Environmental Tracer Studies: Acts as a tracer in research investigating the environmental fate, biodegradation pathways, or metabolic processes of polycyclic aromatic hydrocarbons (PAHs).
• Pharmaceutical Research & Development: Employed in the synthesis of deuterated drug candidates for pharmacokinetic (PK) and pharmacodynamic (PD) studies, leveraging the kinetic isotope effect.
• Organic Synthesis & Mechanistic Studies: Utilized as a building block or probe in synthetic organic chemistry to study reaction mechanisms and isotopic effects.
• Materials Science Research: Investigated for its potential in modifying the electronic or photophysical properties of organic semiconductors and optoelectronic materials.
