Description

Naphthalene-1,2,3,4-13C4 is a stable isotope-labeled analog of naphthalene, where four carbon atoms at the 1, 2, 3, and 4 positions are replaced with the carbon-13 isotope. This compound is essential as an internal standard and tracer in advanced analytical chemistry, enabling precise quantification and metabolic pathway elucidation. It is primarily utilized by researchers and quality control laboratories in the pharmaceutical, environmental, and agrochemical industries for method development and validation in mass spectrometry.

Application

• Used as an internal standard for the accurate quantification of naphthalene and related polycyclic aromatic hydrocarbons (PAHs) via GC-MS or LC-MS.
• Serves as a stable isotope tracer in metabolic and biodegradation studies within pharmaceutical and environmental research.
• Critical for method development and validation in analytical laboratories to ensure regulatory compliance (e.g., FDA, EPA).
• Employed in doping control and sports anti-doping programs for precise metabolite profiling.
• Facilitates kinetic isotope effect (KIE) studies to investigate chemical reaction mechanisms.
• Applied in environmental fate studies to track the transformation and distribution of PAH contaminants.
