Description

3,3'-Dichlorobiphenyl is a specific chlorinated biphenyl compound, a member of the polychlorinated biphenyl (PCB) family. It serves as a critical high-purity reference standard and analytical intermediate for environmental monitoring and research. This compound is primarily required by analytical laboratories, research institutions, and chemical manufacturers engaged in method development, quality control, and the synthesis of more complex chemical entities.

Application

• Environmental Analysis Reference Standard: Used as a certified reference material (CRM) for the calibration and validation of analytical instruments (GC, GC-MS, HPLC) in the detection and quantification of PCBs in soil, water, and biological samples.
• Toxicological and Environmental Fate Studies: Employed in laboratory research to study the metabolism, degradation pathways, and ecological impact of specific PCB congeners.
• Chemical Synthesis Intermediate: Acts as a key building block for the preparation of more complex organic molecules, including specialized polymers and advanced materials research.
• Quality Assurance/Quality Control (QA/QC): Serves as an internal standard or spike in laboratory proficiency testing and method development to ensure accuracy and precision in PCB analysis.
• Regulatory Compliance Testing: Essential for laboratories performing testing to comply with global environmental regulations concerning persistent organic pollutants (POPs).
