Description

2,2',5,5'-Tetrachlorobiphenyl-Ul-14C is a carbon-14 radiolabeled analog of a specific polychlorinated biphenyl (PCB) congener, essential for advanced environmental and metabolic research. This isotopically labeled compound provides a critical tool for precise tracking and quantification in complex biological and environmental systems. It is primarily utilized by analytical laboratories, environmental testing facilities, and research institutions conducting fate, metabolism, and toxicokinetic studies of persistent organic pollutants.

Application

• Environmental Fate and Transport Studies: Used as a tracer to model the degradation, adsorption, and movement of PCBs in soil, water, and sediment.
• Metabolic Pathway Analysis: Enables detailed investigation of the biotransformation and metabolic products of PCBs in biological systems.
• Analytical Method Development and Validation: Serves as an internal standard or recovery tracer in the development of highly sensitive analytical methods (e.g., GC-MS, LC-MS) for PCB detection.
• Toxicokinetic and Bioaccumulation Research: Facilitates precise measurement of uptake, distribution, and elimination rates of specific PCB congeners in organisms.
• Regulatory and Remediation Studies: Supports research aimed at understanding PCB contamination for environmental monitoring and remediation efficacy assessments.
