Description

3,3',5-Trichlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This high-purity reference standard is critical for analytical research, environmental monitoring, and regulatory compliance testing. It is primarily utilized by analytical laboratories, environmental testing facilities, and chemical manufacturers engaged in the development of detection methods or remediation technologies.

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 and food safety testing.
• Environmental Monitoring: Essential 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 profiles of individual PCB congeners.
• Method Development: Serves as a key component in developing and optimizing new analytical methods for the separation and detection of complex PCB mixtures.
• Quality Control Material: Employed as a spike or control sample in laboratory proficiency testing and internal quality assurance programs.
• Regulatory Compliance Testing: Supports testing mandated by agencies worldwide (e.g., EPA, EU directives) to ensure compliance with strict limits on PCBs in various matrices.
