Description

Pcb 209-13C12 CAS NO 105600-27-9 is a stable isotope-labeled analog of PCB 209 (Decachlorobiphenyl), a fully chlorinated biphenyl congener. This compound is essential as an internal standard for the precise quantification and confirmation of polychlorinated biphenyls (PCBs) in complex environmental and biological matrices. It is a critical tool for analytical laboratories in industries such as environmental monitoring, food safety, and regulatory compliance, where accurate trace-level analysis is non-negotiable.

Application

• Internal Standard for GC-MS/MS Analysis: Used for the accurate quantification of PCB congeners in environmental samples (soil, water, sediment) and biota.
• Food Safety Testing: Employed as a reference standard in the analysis of PCBs in food products, edible oils, and animal feed to ensure regulatory compliance.
• Clinical and Forensic Toxicology: Serves as a critical component in method development and validation for detecting PCB exposure in human serum and tissue samples.
• Quality Control in Industrial Hygiene: Used to monitor workplace air and surface contamination in industries with historical PCB use.
• Method Development and Validation: Provides a stable, isotopically distinct signal for optimizing and confirming the performance of analytical methods according to ISO, EPA, and other international standards.
• Research on PCB Fate and Transport: Applied in environmental fate studies to track the degradation and movement of PCBs without interference from native compounds.
