Description

4,4'-Dichlorobiphenyl-Ul-14C is a carbon-14 radiolabeled analog of a key polychlorinated biphenyl (PCB) congener, essential for advanced environmental and metabolic research. This high-specific-activity compound is critical for conducting precise, sensitive tracer studies to understand the fate, transport, and degradation of persistent organic pollutants. It is primarily utilized by analytical laboratories, environmental research institutions, and pharmaceutical R&D departments specializing in toxicology and regulatory compliance testing.

Application

• Environmental Fate and Transport Studies: Used as a radiolabeled tracer to monitor the adsorption, leaching, and biodegradation of PCBs in soil, sediment, and water systems.
• Metabolic Pathway Analysis: Enables the detailed tracking of PCB metabolites in biological systems for toxicological and pharmacokinetic research.
• Analytical Method Development and Validation: Serves as an internal standard or recovery tracer in the development of highly sensitive GC-MS or LC-MS methods for PCB detection.
• Ecotoxicity and Bioaccumulation Research: Facilitates studies on the bioaccumulation and biomagnification of specific PCB congeners in aquatic and terrestrial food chains.
• Regulatory Testing and Compliance: Supports studies required for chemical registration under programs like REACH, EPA TSCA, and other global regulatory frameworks.
• Reference Material for Calibration: Acts as a certified reference material for the calibration of analytical instrumentation in accredited testing laboratories.

Quality Control

Every batch of 4,4'-Dichlorobiphenyl-Ul-14C is manufactured and analyzed under strict quality systems to ensure the highest standards of radiochemical purity, chemical purity, and specific activity. Our products undergo rigorous quality testing, including HPLC and radio-HPLC analysis, to ensure compliance with industry standards. A comprehensive Certificate of Analysis (COA) detailing specific activity, radiochemical purity, chemical purity, and solvent composition is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at recommended temperatures (typically 2-8°C or as specified on the COA) in a dedicated, properly labeled radioactive materials storage area. Due to its highly volatile nature, ensure containers are securely sealed and stored upright in a well-ventilated environment. Keep away from heat and ignition sources.
