Description

2,3,4,5,6-Pentachlorobiphenyl-2',3',4',5',6'-D5 is a stable isotope-labeled analog of a highly chlorinated biphenyl, specifically designed for use as an internal standard in analytical chemistry. This compound is critical for ensuring the accuracy and precision of quantitative analyses, particularly in complex matrices. It is primarily needed by environmental testing laboratories, regulatory agencies, and research institutions conducting trace-level analysis of persistent organic pollutants (POPs) for compliance and scientific studies.

Application

• Internal Standard for Mass Spectrometry (MS): Essential for isotope dilution quantification in GC-MS and LC-MS/MS methods to correct for sample preparation losses and instrument variability.
• Environmental Analysis: Used in the accurate measurement of polychlorinated biphenyl (PCB) congeners in soil, water, sediment, and biota samples for environmental monitoring and remediation projects.
• Food and Feed Safety Testing: Employed as a reference standard in the analysis of PCB contaminants to ensure compliance with global food safety regulations (e.g., EU, FDA).
• Forensic and Regulatory Science: Supports method development and validation for the detection of PCBs in consumer products and industrial waste, providing legally defensible data.
• Toxicological and Metabolic Studies: Serves as a stable isotopic tracer in research investigating the environmental fate, bioaccumulation, and metabolic pathways of PCBs.
• Quality Control/Quality Assurance (QC/QA): Integral component of laboratory QC protocols, including the preparation of certified reference materials (CRMs) and proficiency testing samples.
