Description

Methoxychlor, [Ring-14C(U)] CAS NO 105367-23-5 is a radiolabeled analog of the organochlorine insecticide methoxychlor, specifically labeled with carbon-14 at the phenyl rings for precise tracking in environmental and metabolic studies. This compound is an essential tool for researchers requiring high-specific-activity tracers to investigate degradation pathways, environmental fate, and toxicokinetics with accuracy. It is primarily utilized by agrochemical R&D teams, environmental testing laboratories, and regulatory science organizations engaged in advanced analytical and metabolic research.

Application

• Metabolic and Toxicokinetic Studies: Used as a radiotracer to elucidate absorption, distribution, metabolism, and excretion (ADME) profiles in biological systems.
• Environmental Fate and Degradation Research: Tracks the breakdown pathways, persistence, and mobility of methoxychlor in soil, water, and sediment under various conditions.
• Analytical Method Development and Validation: Serves as an internal standard or reference material in developing sensitive LC-MS/MS, HPLC, or scintillation counting methods.
• Regulatory Compliance and Safety Testing: Supports studies required for regulatory submissions to agencies like the EPA and EFSA, providing definitive data on compound behavior.
• Teaching and Advanced Research: Employed in academic settings for graduate-level research on pesticide chemistry and environmental toxicology.
