Description

2 2' 4 4'-Tetrachlorobiphenyl-Ul-14C is a carbon-14 radiolabeled analog of a specific polychlorinated biphenyl (PCB) congener, essential for advanced environmental and metabolic research. This compound provides a critical tool for tracing the fate, transport, and degradation of PCBs in complex systems with high sensitivity and specificity. It is primarily needed by analytical laboratories, environmental research institutions, and pharmaceutical development teams conducting detailed studies on persistent organic pollutants (POPs).

Application

• Environmental Fate and Transport Studies: Used as a radiotracer to investigate the adsorption, leaching, and bioaccumulation of PCBs in soil, sediment, and water systems.
• Metabolic Pathway Analysis: Enables the detailed study of PCB biotransformation, metabolite identification, and pharmacokinetics in biological models.
• Analytical Method Development: Serves as an internal standard or reference material for calibrating and validating sensitive detection methods like LC-MS/MS or GC-MS for PCB analysis.
• Degradation and Remediation Research: Applied in studies assessing the efficiency of chemical, microbial, or photocatalytic degradation processes for PCB contaminants.
• Toxicological Investigations: Facilitates precise tracking of congener-specific distribution and accumulation in tissues for toxicity and risk assessment studies.
