Description

Naphthalene-Ul-14C CAS NO 71998-51-1 is a uniformly carbon-14 labeled derivative of naphthalene, a fundamental polycyclic aromatic hydrocarbon. This isotopically labeled compound is essential for advanced research requiring precise metabolic and environmental fate tracking. It is primarily utilized by scientists and quality control professionals in the pharmaceutical, agrochemical, and environmental research sectors for tracer studies, analytical method development, and metabolic pathway elucidation.

Application

• Metabolic Pathway Tracing: Used as a radiolabeled tracer in pharmaceutical and agrochemical research to study drug and pesticide metabolism, absorption, distribution, and excretion (ADME studies).
• Environmental Fate Studies: Employed to investigate the biodegradation, bioaccumulation, and environmental transport of polycyclic aromatic hydrocarbons (PAHs) in soil and water systems.
• Analytical Method Development: Serves as an internal standard or reference material in the development and validation of sensitive analytical techniques like Liquid Scintillation Counting (LSC) and HPLC-MS/MS.
• Biochemical Research: Applied in enzymatic studies to understand the mechanisms of PAH activation and detoxification in biological systems.
• Chemical Synthesis Intermediate: Acts as a labeled building block for the synthesis of more complex 14C-labeled compounds for research purposes.
• Quality Control & Reference Standard: Used as a certified reference material to calibrate equipment and ensure accuracy in radiochemical analysis.
