Description

Decachlorobiphenyl is a fully chlorinated derivative of biphenyl, representing the highest degree of chlorination in the polychlorinated biphenyl (PCB) family. This compound is of significant interest for specialized industrial and research applications due to its high chemical stability and specific structural properties. It is primarily utilized as a critical reference standard in environmental analysis and as a key intermediate in advanced material science research. Industries requiring precise analytical calibration or investigating the properties of highly halogenated aromatic systems will find this product essential.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration of GC-MS, GC-ECD, and HPLC systems in environmental testing laboratories for PCB analysis.
• Environmental Research: Used in fate, transport, and degradation studies of persistent organic pollutants (POPs) to understand environmental behavior and remediation strategies.
• Material Science Research: Serves as a precursor or model compound in the development of flame-retardant additives, dielectric fluids, and other specialized polymeric materials.
• Toxicological Studies: Employed in biochemical and ecotoxicology research to assess the impact and metabolic pathways of highly chlorinated congeners.
• Regulatory Compliance Testing: Essential for quality control and method validation in laboratories performing compliance monitoring for PCBs under international regulations (e.g., Stockholm Convention, EPA methods).
• Chemical Synthesis Intermediate: Acts as a starting material or intermediate for synthesizing more complex chlorinated aromatic compounds in specialized organic synthesis.
