Description

Pcb 105-13C12 is a stable isotope-labeled polychlorinated biphenyl (PCB) congener, specifically the carbon-13 labeled variant of PCB 105 (2,3,3',4,4'-Pentachlorobiphenyl). This high-purity analytical standard is critical for ensuring accurate quantification and traceability in environmental and toxicological research. It serves as an essential internal standard for laboratories conducting advanced mass spectrometry analysis, enabling precise measurement of PCB contamination levels. Industries and research institutions focused on environmental monitoring, food safety, and regulatory compliance rely on this certified reference material for method development and quality control.

Application

• Internal Standard for GC-MS/MS and LC-MS/MS analysis of PCBs in environmental samples (soil, water, sediment).
• Quantification and method validation in food safety testing for PCB residues.
• Calibration standard for high-precision analytical instruments in contract research organizations (CROs) and regulatory labs.
• Use in toxicology and metabolomic studies to track the fate and transformation of PCB congeners.
• Quality control reference material for the production of certified reference materials (CRMs).
• Spiking standard for recovery studies in complex matrices like biological tissues and industrial waste.
