Description

3,3',4,4'-Tetrachlorobiphenyl-Ul-14C is a carbon-14 radiolabeled analog of a specific polychlorinated biphenyl (PCB) congener, essential for advanced research and analytical applications. This compound is a critical tool for studying the environmental fate, metabolic pathways, and toxicokinetics of PCBs with high precision and traceability. It is primarily utilized by research scientists and analytical laboratories in the fields of environmental science, toxicology, and analytical chemistry for tracer studies, method development, and regulatory testing.

Application

• Environmental Fate and Metabolism Studies: Used as a radiotracer to investigate the degradation, transformation, and bioaccumulation of PCBs in environmental matrices and biological systems.
• Analytical Method Development and Validation: Serves as an internal standard or reference material in chromatographic (GC, HPLC) and mass spectrometric methods to ensure accuracy and precision.
• Toxicological Research: Enables precise tracking of the congener's distribution, metabolism, and elimination in in vitro and in vivo studies to understand its toxicological profile.
• Regulatory and Compliance Testing: Supports testing protocols for PCB contamination in accordance with environmental protection agency guidelines worldwide.
• Biodegradation and Remediation Research: Acts as a tracer to monitor the efficiency of microbial or chemical remediation processes targeting chlorinated biphenyls.

Quality Control

Every batch of 3,3',4,4'-Tetrachlorobiphenyl-Ul-14C is manufactured and analyzed under strict quality protocols to ensure identity, purity, and specific activity. Our quality commitment includes verification via radio-HPLC and GC-MS to confirm radiochemical and chemical purity. A comprehensive Certificate of Analysis (COA) detailing specific activity, radiochemical purity, analytical methods, and solvent information 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) to maintain stability. Due to its highly volatile nature and light-sensitive properties, appropriate handling in a controlled environment is advised. Always refer to the specific storage instructions on the product label and safety data sheet.
