Description

2,4'-Dichlorobiphenyl-D8 is a deuterated internal standard critical for precise analytical quantification. This stable isotope-labeled compound is essential for ensuring accuracy and reliability in trace-level analysis, particularly in complex matrices. It is primarily used by analytical laboratories and researchers in environmental monitoring, food safety, and forensic toxicology for the quantification of polychlorinated biphenyl (PCB) congeners.

Application

• Internal Standard for GC-MS/MS Analysis: Used as a quantitative reference for the analysis of 2,4'-dichlorobiphenyl and related PCB congeners in environmental samples.
• Environmental Monitoring: Enables accurate measurement of PCB contamination in soil, water, and sediment for regulatory compliance and site remediation studies.
• Food Safety Testing: Employed in the quantification of PCB residues in food products, animal feed, and edible oils to ensure consumer safety.
• Forensic and Clinical Toxicology: Supports the precise determination of PCB exposure levels in biological samples for human biomonitoring and forensic investigations.
• Method Development and Validation: Serves as a key component in developing and validating robust analytical methods according to ISO, EPA, and other international standards.
• Pharmaceutical Impurity Profiling: Can be utilized in trace analysis for potential chlorinated organic impurities in active pharmaceutical ingredients (APIs).
• Quality Control in Reference Material Production: Used in the preparation and certification of certified reference materials (CRMs) for PCBs.
