Description

13C12-4-Chlorobiphenyl is a stable isotope-labeled analog of 4-chlorobiphenyl, a key compound in the study of polychlorinated biphenyl (PCB) environmental fate and metabolism. This high-purity labeled standard is essential for ensuring the accuracy and reliability of analytical methods, particularly in mass spectrometry, where it serves as an internal standard for quantification and quality control. It is primarily utilized by analytical laboratories, environmental testing facilities, and research institutions engaged in trace-level analysis of persistent organic pollutants (POPs) for regulatory compliance and scientific investigation.

Application

• Internal Standard for GC-MS/LC-MS analysis of PCBs and related contaminants.
• Quantitative reference material for environmental monitoring of soil, water, and biota.
• Metabolic and degradation pathway studies in environmental and toxicological research.
• Calibration standard for high-precision analytical instrumentation.
• Method development and validation for regulatory compliance testing (e.g., EPA methods).
• Quality assurance/quality control (QA/QC) programs in analytical laboratories.
• Isotope dilution mass spectrometry (IDMS) for achieving highest accuracy in quantification.
