Description

1,1'-Biphenyl-1,1',2,2',3,3',4,4',5,5',6,6'-13C12,2,2',3,3',5,5',6,6'-Octachloro- is a highly specialized, isotopically labeled derivative of octachlorobiphenyl, a compound of significant interest in environmental and analytical chemistry. Its core value lies in its utility as an internal standard or reference material for mass spectrometry, enabling precise quantification and trace analysis of polychlorinated biphenyl (PCB) congeners in complex matrices. This product is essential for research laboratories, environmental testing facilities, and regulatory bodies requiring the highest level of accuracy in contaminant monitoring and method development.

Application

• Internal Standard for GC-MS/MS Analysis: Primary application for the accurate quantification of octachlorobiphenyl and related PCB congeners in environmental samples (soil, water, sediment).
• Method Development and Validation: Critical for establishing and verifying analytical protocols in compliance with EPA, EU, and other international standards for persistent organic pollutants (POPs).
• Metabolic and Degradation Studies: Used as a stable-isotope tracer in research to investigate the environmental fate, biodegradation pathways, and metabolic products of PCBs.
• Quality Control/Quality Assurance (QC/QA): Serves as a certified reference material (CRM) or quality control spike to ensure the reliability and precision of analytical data in contract testing laboratories.
• Forensic and Source Identification: Aids in the chemical fingerprinting and source apportionment of PCB contamination in environmental forensic investigations.
• Calibration Standard: Used to prepare calibration curves for high-resolution mass spectrometers, ensuring minimal interference from the sample matrix.
