Description

1,1'-Biphenyl-1,1',2,2',3,3',4,4',5,5',6,6'-13C12, 2,2',3,4,4',5,5'-Heptachloro- (9Ci) is a uniformly carbon-13 labeled isotopologue of a heptachlorinated biphenyl, serving as a critical internal standard and tracer in advanced analytical chemistry. This high-purity, isotopically enriched compound is essential for ensuring the accuracy and reliability of quantitative analyses, particularly in complex matrices. It is primarily utilized by analytical laboratories and research institutions in the environmental monitoring, food safety, and forensic toxicology sectors for the precise detection and quantification of polychlorinated biphenyl (PCB) congeners.

Application

• Internal Standard for Mass Spectrometry (GC-MS/LC-MS): Used for the accurate quantification of PCBs in environmental samples (soil, water, sediment) and biological tissues via isotope dilution mass spectrometry.
• Metabolic and Environmental Tracer Studies: Enables the tracking of specific PCB congener transformation, degradation pathways, and bioaccumulation in environmental fate studies.
• Quality Control & Method Validation: Serves as a critical reference material for validating analytical methods, ensuring compliance with stringent regulatory standards like EPA methods.
• Forensic Analysis and Food Safety Testing: Employed in the precise determination of PCB contamination levels in food products, feed, and consumer goods to meet global safety regulations.
• Pharmaceutical Impurity Profiling: Can be used as a labeled standard in the analysis of halogenated organic impurities during drug development and manufacturing.
• Certified Reference Material (CRM) Production: Acts as a key component in the preparation of certified reference materials for laboratory proficiency testing and instrument calibration.
