Description

2,3'',4,5-Tetrachlorobiphenyl is a specific polychlorinated biphenyl (PCB) congener identified by CAS NO 73575-53-8. This compound is of significant importance as a high-purity analytical standard and reference material for environmental monitoring and toxicological research. It is primarily needed by analytical laboratories, environmental testing facilities, and research institutions involved in the study of persistent organic pollutants (POPs), PCB metabolism, and regulatory compliance testing.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration and validation of analytical instruments like GC-MS and HPLC in environmental analysis.
• Environmental Monitoring: Crucial for the accurate quantification and profiling of PCB congeners in soil, water, sediment, and air samples to assess contamination levels.
• Toxicological Research: Used in scientific studies to investigate the specific biological effects, metabolic pathways, and toxicity mechanisms of individual PCB congeners.
• Method Development & Validation: Serves as a key component in developing and verifying new analytical methods for POP detection and quantification.
• Quality Control & Assurance: Employed in laboratory QC protocols to ensure the accuracy and precision of PCB testing results for regulatory reporting.
• Regulatory Compliance Testing: Essential for industries and consultancies conducting mandated testing to comply with international regulations on PCB levels (e.g., Stockholm Convention, EPA methods).
