Description

2,3,3',5,6-Pentachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a well-studied class of synthetic organic chemicals. This high-purity reference standard is critical for analytical and research applications requiring precise identification and quantification. It is primarily utilized by environmental testing laboratories, regulatory agencies, and academic researchers focused on legacy pollutant analysis, toxicology studies, and method development.

Application

• Environmental Analysis Reference Standard: Serves as a certified calibration standard for the accurate quantification of PCB congeners in soil, water, sediment, and biota samples via GC-MS or GC-ECD.
• Toxicological Research: Used in laboratory studies to investigate the specific biological effects, metabolic pathways, and persistence of individual PCB congeners.
• Method Development & Validation: Essential for developing, optimizing, and validating new analytical methods for the detection of persistent organic pollutants (POPs).
• Quality Control & Assurance: Employed as an internal standard or spike in laboratory QC protocols to ensure accuracy and precision in PCB analysis.
• Regulatory Compliance Testing: Supports testing to comply with international regulations (e.g., Stockholm Convention, EPA methods) governing PCB levels in the environment and consumer products.
• Forensic Environmental Chemistry: Aids in source identification and fingerprinting of PCB contamination in environmental forensic investigations.
